I've been going thru the kart and doing a lot of research and reading. The wheel bearings appear to be brand new. No issues or play that I can find. What I did find was this specific kart was designed to be run with 3" to 3 1/2" wide front tires. Kart is currently running 4 1/2" wide tires. I think there lies my problem.

Sure seems like that’s your issue. All documentation from that era shows skinny tires on karts and open-wheel race cars as well. I’ve seen some tire designs wherein the tire carcass is wider than the usable tread or contact patch, giving a very “pinched” look profile.

This is not the most extreme example but an idea:

That’s about a 2” to 2.5” tire contact patch.


One might conclude then, that there wasn’t much tire traction as we enjoy today and I guess that’s true, but that was by design. These rear engine karts love skinny tires as they were driven to the limit of the tires adhesion and drifted/oversteered/“tail wagged” through the turns.

There’s some good vintage karting videos on YT.

I appreciate your post Hellion. Thanks. I think that I've located the correct vintage tires to fix this problem. I've been chasing parts to put a period correct 2 stroke engine on the kart. With assistance from the vintage racing kart community, I have an original UNI mount with mounting hardware (rubber mounts) coming my way. My goal is to put this kart back to period correct configuration and condition.

So, Rupp's were made in Mansfield, Ohio
…& these Lancer karts were made in a factory in Findlay, Ohio

Wow, seems like a lot of karts were built here in Ohio

Q:
Can you feel any flex or torsion-ing when you ride?

How does it handle?

...more information please

From what I'm learning, Rupp and Lancer had an agreement and Rupp manufactured karts for Lancer for a period of time.

It is a pretty cool kart. In relatively decent shape. When I went to look at it, most of the key pieces were there. I'm very, very far from being any type of expert on vintage karts!!! LOL. Doing a lot of research and learning. However, I have done a lot of restoration work on old vintage cars, boats and cycles over the years. Basically, I'm a sucker for this kind of stuff! Kart was being turned into a kid's yard kart. I didn't want to see the kart end-up that way!

On to handling and ride. When I got the kart home, wouldn't run as it had a lot of initial issues with the engine and steering (too wide tires). For example, clutch wasn't fixed on the crankshaft (floating), brake rotor loose, engine wouldn't start, can't turn w/o right spindle arm rubbing on tire and pulse pump/carb/fuel bowl amiss. I finally got it running, but, you can't turn at any speed w/o engine quitting. So, I would wind it up from the top of a hill, aiming down hill, then take the kart into a left turn hard, engine quit, but the kart would follow thru and I could get a feel for it's handling. Handled pretty good! No flex at all that I can feel in the frame. It has sticky modern kart tires on it so you can't slide it around turns, especially w/o engine running. On straightaways, I was able to get the kart probably up in the mid-40 MPHs with the clone engine. That is where I quit for now. I'm searching for vintage kart parts now to get it back to period correct condition. The clone engine is coming off and a 2 stoker is going to go on.

if you intend to strip it down in the process..
(finding hidden rust and or technical kinks)
please take as many as good photos as possible..

would be nice to get some dimensions as well
distance between swingarm picot and rubber grommet would be interesting to me (just to get a better idea)
well.. assuming that is a rubber grommet (medium to hard density rubber..)
would be interesing to know it's exact shape as well...
looks like it's a part that
a) can uv-rot
b) is not exactly a std hardware store part
c) likely isn't easy to find in vintage part stores
and most importantly
d) would be relatively easy to reproduce on a TPU 3d printer.

Sooo in case you can provide detailed pics and dimensions,
I would love to make a 3d model of that grommet.. just as a backup plan

I plan on taking detailed pics of everything as I disassemble.

sid - I'll PM you as I get into the disassembly process.

I've got an original style UNI mount coming with the original style rubber isolation mounting hardware. I can't wait to see that piece.

Parts chasing is turning out to be a little be more difficult than I originally anticipated.

Yes, detailed pics, measurements, dimensions
...& even personal commentary on ...anything & everything you see, notice etc.

Started taking the kart a part yesterday. Got the clone engine off the kart. I also received the Uni Mount for the engine, amazing piece! See attached pic. I'll continue to post pics and commentary as I go.

Good Afternoon All - as I said, I'll post information and pictures as I progress with this kart project. Especially at points where I feel like I'm making good progress or stuck and not making any progress. LOL! Here are some of the major parts that I've located and bought, so far. I posted a picture of the Uni Mount last post. Been looking very seriously for a good West Bend 820. So far, this engine looks pretty good, no stripped bolt holes or bolt heads, broken parts or damage, no re-welds, etc..., that I can easily find in a quick once over. Only time will really tell when I tear it down and really check it out! I've had a lot of help and advice from friends into vintage kart racing. Without them, I wouldn't have gotten very far! Have some more parts coming. Hooray! We're getting close to mocking parts up for fitment before final breakdown and parts restoration.

That Westbend looks SO COOL!
I still want to mess around with a vintage 2 stroke on a kart someday.

Thanks for your comment on the WB 820. I think that they are cool also!!!

This showed up Saturday. Really hard to find a good Chilton tank! I'm getting closer to getting all the parts necessary to get this kart back together.

Great looking engine sid!!! Appreciate your comment on the tank. It was amazingly hard to find a nice one. Only had to extend the mortgage on my house for an additional 10 years to pay for it! LOL.

My kart engine will never look that good. Hopefully, if all goes well, I plan on running the kart in a couple of vintage kart events in 2020.

I've almost got enough parts to start mockup assembly of the kart. I'll update with pics once I make some additional progress.

hehe I imagine that tank's price is one of those things
you're wife only needs to know half the truth about to get mad

Yeah that engine is true eye candy.. wish it were mine
(just found that pic a few years ago and saved it because of drool )

Now a twin carb intake manifold (75 bucks) a second carb (50-70 bucks)
the GEM scopp (90-120 buckaroos) and the exhaust (say 70)
still less than that tank LOOOL
by the way that'S the motor mount I was talking about previously
(the one that slaps onto your tabs floating on the axle)
you got a a very early one (1960? or such)
one I personally only ever remember seeing on an old Blackhawk poison arrow
(short: you got the more expensive version of motor mount)

Anyways... karts like that are a progress not a product..
you can add more shine later on 2020, 2021 who cares as long as you enjoy working on it
