It actually has a lower tensile strength than #35.
If you want stronger chain, go with #40 or #420.

If it’s the standard 30 series TC, the jackshaft is...

Well if the engine is fresh, then I wouldn’t worry about the 10.8 lb springs. 10.8 are the stock replacement springs. I just thought they might be worn out if you have been running at 5200 rpm for a...

It’s 10 :1 gear ratio.
10 on clutch to 20 on JS.
Then 10 on JS to 50 on rear.

5200 RPM is about 29 mph with 10 :1 gear ratio and a 19” tire.

Shoot for a total reduction of about 7.2 :1 and it...

I just looked and was surprised to find out that not all those Tillotson engines come with Flywheels. I was previously under the impression that they came with Flywheels rated for 10k rpm.

Remove flywheel. Punch the shaft out of the block. Use a bolt to plug the hole. I think I tried 1/4-20 first, but ended up tapping for a 5/16” bolt.
