He said it had no compression.
Suck, squeeze, bang ,blow.
No squeeze.
So it just sucks.

But that can be fixed. Then it wouldn’t only just suck.

"Just needs a clutch" he said.
Something didn't feel like just a clutch. There was no drag or friction or drag in any gear. The clutch felt normal. There were 45 to choose from.
This one was just perfect, if l can make it work without a butt load of money.
So l set out to find the problem. I started with the clutch since that what he said. Well the clutch is fine. I got that sinkin feeling when l grabbed the output shaft and it spun freely. In all 6 gears.
No noises grinding, binding it SHOULD work!
WTF?
Broken shaft? Not likely. I investigated further and wadda know....
Some dummy either forgot or didnt tighten the big azz nut that holds the sproket on.
The sprocket was just sponnin freely on the threaded portion at the end of the shaft.
The chain is under a complex cover so the problem was not easily seen.
The nut is long gone, so i slid the sprocket back on and went for a ride. Short ride cus the sprocket fell off again.
No threads were harmed in this fiasco.

As part of the educational program we participate in here at MTL We present the following.
You will notice the term"butt load" used above.This subtle inclusion was to lead to a full explaination as a public service message, for our young fans. Sadly l forgot the exciting conclusion. So without further delay:
google it if ya be a doubter.

The design/engineering department here at MTL has been studying the the project and asking questions about materials/parts/tooling, a bunch of BS mostly. One question did initiate some thinkin. Heres the dilemma:
Normally on a kart the engine is "moved to adjust the chain, I believe.
On a motorcycle the axle is moved to adjust chain tension.
This project neither of those is practical. So what to do? A "chain tensioner"? I can see that working if....
Would it have to be like a derailer thingy on a bycycle?
Both the engine and axle are stationary in this instance.
So I put the question to our panel of experts. I am confident that we can come up with a clust.... errr Ahhh, I mean suitable solution.
What say YE?

Is your engine and axle on the same frame? Or are you gonna run a swing arm.

no swing arm. IRS with a stationary center section.
engine/trans/ axle all on the same frame solid mounted.

Are you familiar with KJ racing? He builds his crosskarts with a chain driven IRS hub.

Similar to this one.
yeah i look at KJ's stuff, mainly for ideas. Remember, my inner cheapskate won't let me buy anything that l can make. This whole thing is about makin shyt. I have lots a time and little cashmm due to having way toomany interests/hobbies/wishes.

Do you have camber issues as the system travels.
Your knuckles pivots and CV joint arent very "inline"
Other than that, the hub looks robust.

It is not the perfect suspension, but it actually works purdy good.
it's got 12" of travel (potentently). There were compromises made....
and i really didnt have a clue.
back to the chain adjuster?

A spring tensioner with a derlin roller would work well.
Set your engine where the chain is just a tad slack.

What l'm thinkin.
More than you care to know. Thats a funny story actually. By sharing this srory, l officially submit my application for "overkill masters".
when l retired there was some unsold inventory that came home with me.
Among those item were some 6020 bearings. (Googlt it)
those bearings have a 100mm bore. 150mm OD.
the CV shsfts have a 100 mm OD hub. Well wadda ya know. A two stack fit perfectly (width) ID and OD
Since l saw a video on Utube U how to do it, l decided to match grind 'em into an angular contact pair. Well, it worked just as the you tube proffessor said.
so now there are one pair of bearings on each rear wheel, 4 total.
Heres the good part, each one of those bearings has a dynamic load rating of
14,xxx lbs.
