Go Kart Go!

Too young for a driver’s license but mechanically inclined and anxious to be involved in things auto-motive I was thrilled to have a Go Kart.  I spent many hours in the garage wrenching, tinkering, and learning mechanics. The main excitement of course was the driving. Neither machine nor I were approved on regular streets obviously so a fav venue was the  Kerman Kartways.  A 1/3 mile road course with many tight turns, a broad easy banked sweeper and of course a front straightaway created delight.

My *new* Kart was acquired from an answered ad in the local classifieds.  Current owner was away on military duty and his family charged to sell it for him. The selling representative knew little about the particulars but it was obvious that it had been a race kart in its heyday and I had visions therefore  of attaining great speeds. There was no test drive; just assurances that it ran and nearly $300 was exchanged.

The frame (circa 1963 or ’64) by Kavalla I promptly repainted in Competition Orange. Chrome & Neoprene Steering Wheel. Foam padded and naugahyde upholstery.  Aluminium floor pan. There were some exotic bits such as magnesium spyder-type wheels with Carlisle Slicks, and a disc brake on the aluminium live axle chain directly driven by a hot little MC9 McCulloch.  This engine was a 2 stroke designed for power with light weight. Since there wasn’t a clutch for ease of starting, weight mattered. The procedure was to aim front wheels in the desired direction, Lift the back end high in the air with one hand on rear frame rail and the other guiding and pushing on the seat frame top. While jogging at a good clip you would then lower the back wheels onto the tarmac and jump in. The forward momentum and sudden weight on wheels was enough to spin the engine and with a quick stab to the throttle and possibly a deft hand [as choke] over carb intake it would ‘catch’ and away you’d go.

It was necessary to continually adjust fuel / air mixture ratio for prevailing conditions and max performance. This was achieved by screw in/out needle valve on the carburetor. Alternatively, fine tuning could be done while underway. Shifting your body partially and reaching back with fingertips to tweek was common place. If too rich, there was severe power loss. This adjustment was crucial because too lean and piston and cylinder would overheat and  eventually fail for lack of lubrication (oil is mixed with fuel).  The adjustment per the manual was to set at 1 1/4 turns open initially as a baseline.

This didn’t work for my application and I was perplexed. The engine would only run properly starting [lean] at about 1/2 turn. This was unsettling because I fully understood the risk of sticking the motor. I only realized years later what the seller failed to communicate: The carburetor had been [oversized] jetted for racing alcohol. Alcohol gives a power gain but at increased flowage.  So, with the carb set up in this manner running regular pump gas was a downer. Had I run the special fuel instead of gasoline, I could have flown!

Just as well probably. Speed equates to risk. Still, it was a ball of fun in a helmet.

Go Karting out in country — off road.

 

sloppy shifter

Something was amiss as 2nd was difficult to engage without clashing and then it would pop-out of gear under load. Poorly adjusted linkage? Bad syncro? Big overhaul?

remains of bushing material

None of the above. Inspection of the shift lever arm and yoke revealed that the rope-like material originally used for bushing had perished. The shift lever bearing (#7 in the Fig.) was sloppy and wobbly loose in its retaining bracket and no longer capable of fulfilling its function as a pivot axis. Fresh bushings were sourced.

This was a bit of a challenge because the original gearbox with Hydrak fluid coupling and a steering column mounted shifter had been abandoned early on as problematic and difficult to maintain.  Hydrak was an early response to the American export market that expected and got automatic transmissions in their higher end car models.  This answer to clutchless shifting (1940’s technology by comparison to fully automatic) was transitional and some owners regressed to the  more robust standard (fully manual) shift option.

The retrofit parts list would have been extensive and since the conversion occurred almost 50 years ago, I had no idea which parts were used. I assumed that some may have come from a donor car. The clue was the 3 bolt pattern in the  shift bearing retaining brackets pictured. Browsing  parts manuals of similar vintage models I deduced (correctly) that the shifting linkage was transplanted from the type 190 SL.

Wheels and Tires Renewed

dry rot neglect
Despite having gone completely flat during many years of storage and with rims pinching sidewall, they took air and still managed to hold inflation.

They last hit the road in 1988 and had been resting on rims, leaves, and dusty cement floor in dry rot neglect.

As you can see the old tires were aged. Visible in the image are sidewall checks and splits. In other areas the tread has separated from the tire casing.

 

 

 

NOS tires  were sourced and shipped. The originals delivered with the car as new would have been the optional  weißwandbereifung [white-walls] that were in vogue in the USA market during that era. White-walls are exceedingly popular for collectors but I consider them an overly used gussification;  (ditto for continental tire kit installations, added rear fender skirts, and dangly things from the inside rearview mirror).

This Michelin “X” tube type radial is period correct and to my taste an authentic european sporting look.

Never the Right Tool #*!!

A statement of frustration blurted by my Father when attempting a household repair. I think his meager tool box consisted of pliers, crescent wrench, hammer,  pipe wrench and a couple of screwdrivers and bailing wire; so, when the odd DIY task such as connecting the new dishwasher came along his kit was lacking. The lament always signaled impending defeat and preceded the interruptive trip to the hardware store.

 

Flash forward. I have a rather massive 14mm Allen Wrench used to remove the hex pattern oil fill/drain plugs on my vintage car.  This tool allows me to service fluid level on both the transmission and differential. Almost. It turns out that this trusty wrench is too bulky to access the fill plug on the rear axle.  baulky allen keyThe tool won’t physically fit between the plug and the adjacent gas tank. Consternation follows. What was the method to pull this plug? What tool did I use before and where is it now? Had I ever actually serviced this item? My rolling chest of drawers, while hardly complete, is still a far cry from the random assortment in my Dad’s day. Still, after rummaging through, I realized that I didn’t own the proper tool; a short straight hex key on a 3/8″ socket.

Instead of halting the operation, getting cleaned up, and driving to the Auto Parts House (the proper thing) but in grand gesture toward Dad’s way — I improvised.

Staring thoughtfully at the internal hex pattern in the plug it occurred to me that a hex head bolt (male) might just be the ticket.tight fit 14mm is nearly equivalent to .5″ and my salvaged supply of old bolts might offer a match. I eyeballed a handful of candidates and then began to measure in a more precise way with Calipers.  A lag bolt with head measuring .56″ was too great a span, another sample, inadequate. I didn’t want to louse up the female end of the plug. A bolt head that was too small would surely strip it.

An old carriage bolt turned up as suitable and with vice-grips pliers for leverage I was able to cleanly extract the unmanageable plug.

Exasperation avoided and a run to the store annoyance averted, when next surfing Amazon I will order: “The Right Tool”

It’s a Goner

My initial concern was one of monetary loss ($750). My connected device was gone. Misplaced. Standing-by in the left front pocket of my trousers, normally, it lends a sense of form against my thigh. An occasional pat or  brush of hand reassures that it is secure. Previous experience told me that this was a good location. Too rigid for a hip pocket and prone to spill from an open shirt pocket; it had only slipped a very view times when seated within the soft confines of sofa or pillow chair. One naturally makes a wallet / phone check upon exit.

The last reaffirmation check revealed that the usual location was empty. Confounded, I checked the other pocket possibilities. Nope. It was missing.

Recovery would be a puzzle. I would have to recollect when last handled as well as account for all events and movements since. A window of confidence was roughly 45 minutes but then you realize that a general summary recollection is clear but all of the small ‘witness’ details insignificant at the time, are brain stored in short term low level memory. Initially I was assuring myself that my phone was likely safe and would “turn up” but no; it took hours of revisualization and introspective thought to reconstruct.

The other pilot and I were leaving the airport on foot for an impromptu round trip to Cooper’s Island but not before a quick pit back at the jet to retrieve hat and sunblock. I reckoned that while crouching beside open suitcase in the bag compartment perhaps it had deposited there (False hope.  It hadn’t ).

Early on along our route we encountered two young girls opposite direction who were keen on our uniforms. We side stepped clear of the road and had a pleasant chat on the shoulder  with one being a Londoner and the other a Local. Before carrying onward there was a FB friending and group Selfie. Did I withdraw my (camera) phone and mis pocket opening? Did it fall silently into the deep grass? I would later retrace this 1/2 mile stretch trying unsuccessfully to recall the exact spot we all stood. Sweep scanning blades of  green for a glint of case or reflection on gorilla glass a dark thought occurs. Pickpocket! (Possible I suppose but a stretch)

Having arrived at the park entrance and while stalling for a bit while the other fellow captured some white sand beach setting photo I angled my leg to retie shoe lace. (squeezed from pocket opening) Was it the first beach or the next? Which fence railing?

24 hours had elapsed and I had gone back twice to search replaying everything but to no avail. I had to exhaust the possibility that it wasn’t just laying there undiscovered. After all, an opportunist would surely have attempted to access and the clever Find-my-Smartphone feature would broadcast its coordinate location. Alas, being out of country as I was the phone’s antenna was in airplane mode and therefore off network. A thief would merely have to wait it out knowing that the owner would probably remotely erase the device contents eventually after losing hope.

In fact, I was seriously poised to do that very thing. A data breach would be ugly with personal information of every kind risking exposure. The phone is locked by 4 digit PIN but with time and sophistication a good hacker might succeed. I learned that while the data wipe feature would allay these concerns, this option would also kill any possibility of tracking or easily identifying the device. In fact, it would make it possible for the discoverer to activate a fresh install — finders keepers.

Disgusted that I lost control of my property, resigned to writing off the asset as a loss, disappointed in having failed to find it, soul searching; why I am such a slave to the thing in the first place. Like so many by habit, I find myself staring at the small screen during every possible moment. How to go about replacing? Perhaps now is a good time to go cold turkey and kick this addiction?  I’m part way there.

By the next day I’ve traversed many states of mind; bummed, gloom, depression withdrawal but I’m less frequently checking the empty pocket or having phantom sensations. I’m actually gazing about spaces and at people during the idle moments.

By now the lost phone should be at lo-batt or nearly depleted. Seriously ready to Nuke…

Reunited

[spoiler alert: review the previous post first]

The CSR behind the desk at airport FBO doubted that I’d ever see it again. It had not shown up at their lost & found. I hadn’t expected it to. Whoever picks it up will keep it, she says. Just the same, I was wondering if perhaps an honest citizen might  turn it in. I had asked a Park Service  maintenance employee if they knew and the suggestion was floated that I try the local Police Substation. The CSR was dubious and I was primed to agree but then somehow we decided; let’s try.

She picked up the phone. I was only party to the one sided conversation but when she started relaying bullet questions from the other end such as: What color is it? and: What is the screensaver? (Sailboat) and then: What is the name on the boat? it became crystal there was going to be a happy outcome.

The CSR personally drove me over to claim it. I would have liked to have rewarded the soul who turned it in. My faith in humanity is restored. May that individual enjoy their good Karma.

I credit good police work. The officer had actually called over to the Bermudian Maritime Authority and determined that the yacht pictured from the lock screen was not in country. I explained that a year ago that it had been and the official confirmed this to be known.

BTW, I’m off the wagon but trying to be diligent about usage. It goes without saying I’m installing a collar and chain 😉

leave less to chance

What can go wrong WILL go wrong. sorry keyI only had the one key and it was really looking past it. Not visible by thumbnail image is a hairline crack across the blade; a victim of too many bendings from body bumps and slams (the engine control panel and ignition switch is located in the companionway and the key protrudes) It might eventually break off (in the switch!) or go missing. Either way, SOL.new switch

I took the original to a locksmith or two to see about cutting a new one. Out of the zillion types onhand, none could procure a suitable blank. Yanmar no longer provides for replacement keys. Solution: Order the entire switch. Comes with an extra to boot.

Countryside Discovery

I really expected to be chasing down this repair job from vendor to vendor trying to track down the right outfit for the job. I got lucky and scored first try.  I knew that I was ill equipped tool wise and vague on metallurgy. My Sheet Block, built back in the day, sheet blockwas non-replaceable.  The fixture was warped; bent by the powerful loading of the jib sheet when a pivot pin partially backed out.  A massive bench vice or a hammer, or a heating torch or all of the above would be needed. Finding a metal fabricator with a Google search led me, not to an enterprise in a business park, but a guy named Johnny at a leanto shed in a rural setting on a dirt road.  He went right to work (how rare is that? but halfway through the job I realized that my credit card would be of no use out here and I began to search pockets to see if they had Cash!).

hammer persuasion

Johnny persuaded the heavy piece back into shape and the pin was straightened with several strategic blows and aligned.

Next, Silver Solder was applied to hold the pin in place. If this proves an area of weakness, I may peen the housing bracket or secure the pin with a set screw. Turns out that the entire mass of metal is cast Brass with a Copper plated finish. This explains the malleability and the  blue green oxidation. Old school. I don’t think they make ’em like this any more.

I mentally noted a placard sign affixed to the wall that proclaimed the shop rate at $65/hr. with a minimum job amount of 30. I had all of 26 dollars in 3 Fives and the rest Ones. Uh oh…  I asked what I owed. A delayed response gave pause and I interjected that I had only 26 bucks on me. Johnny said I’ll take 25 of those.

new halyard Victory

The easier method is to whip the two ends together – new to old, and haul away on the old halyard until the new rope takes its place. mast

The existing halyard was AWOL however, sheared due to chafe when the mainsail failed and flogged, so a raw procedure was required using gravity. Climbing 50′ above deck to the masthead with the new cordage takes some preparation for planning. Have the necessary items with you as you arrive at the top because it does involve physical effort to ascend and descend. It would be good to only have to make one  safe roundtrip.

The 1/2″ (12mm) X 150′ Braided Rope replacement, while quite flexible, is a bit unwieldy so a much smaller lead line was attached to a spliced end to guide the big rope over the sheave at the knot to splice lead weights masthead and down through the hollow interior of the mast itself and then out the shield plate exit at its base. This lead line is light  in weight so to keep it straight and true for its descent, a length of nylon fishing line with small lead weights was fashioned. This was probably overkill. 50′ of fishing line might have done the job ( but I imagined that I would arrive at mast peak with a snarled mess of knots to sort). The biggest challenge as it turns out was passing the lead weights over the sheave within the confines of the mast head. There was scarce wiggle room for line , mass of weights, and one finger to poke, prod, cajole,  through the narrow passage. The weights tended to rear up straight falling backwards over the top of themselves. I needed them to fold over the arch of the sheave and head downward. Finally, after many failed tries and with the insertion of a second finger to manually spin the sheave I was able to finesse the lot inward and onward.

The next task was to temporarily secure the lead line at the top. masthead heightOur friend Gravity, while assisting the placement of the feeder line would be just as happy to pull it all back down again once I turned loose of it. There was an elegant idea to use lightweight masking tape. It would have torn away freeing the line after a moderate tug.  An excellent solution but I lost my roll of tape to the silty bottom of the Marina when it got away from my tool belt. Not wanting to tie a knot, which would necessitate a revisit, I wrapped the exposed free end of the line around the backstay knowing that I could unwrap from below. The friction was enough to stabilize and hold in place as I commenced descent.

Finally a slim hook was used to probe the hollow spaces and the leader fished out of the mast at deck level.  The Ahhhh moment was  grasping the spliced end of the new halyard and knowing in the  success of the moment. probe
