Ratio used is 40:1. I didn't use the cylinder gasket; had a squish of 0.022" and i made several measurements around the piston. Could that ring have been formed after the bearing failed?

Anyone have a rod bearing fail? Looks like there's a little discoloration from heat. Plenty of metal shaved/chipped off and made it up to the top. I had 5-6 tanks through the saw.

Oh, I was measuring the gap at the outer bearing race. I couldn't center the crank in the case because the PTO bearing was a bit proud of the inside case wall. Now I'm wondering if I needed to adjust the bearing instead. Well, I already filed the crank a bit to get it to spin.

Ok. I'm at the point where i need to modify the bell. I was worried that modifying the bell would cause an imbalance. Good to know it's been done before. I must have missed that post. Thanks!

Yeah, it's centered at .02" gap on each side of the case but the crank can barely turn.

On the flywheel side, looks like there's a bit too much paint and it interferes with the crank counterbalance. I'll have to sand it out a bit. Bummer.
