That’s what I got so far. Have the degree wheel mounted as well.
The piston and head don’t look as bad as I thought they would. I haven’t taken the cylinder off yet though. I guess there’s no reason I can’t?

Also,
I put a new bearing in the CVT cover recently and when I just went to take the cover off the end of the shaft that goes into the bearing was seized in the bearing and I had to carefully pry and finagle it off. Going to order a new one along with a new front half because I broke the blade off of the current one. Anyone have a link to a good front half?

Never seen such a neat hole in a piston? What kind of oil and ratio?

40:1 Motul 710
It’s hard for me to believe that it was while I had it that this happened. Maybe it got worse or something.m, but I bought this non running and it has always been kinda sluggish ever since I got it running. Amazing that I’ve been able to put so many miles on it!

Maybe it’s time I just get that cheapo 70cc kit and forego the Polini until I’m bored

I might as well just get the cheap kit I was going to get in the first place if I buy a new head. There are a couple deep gouges and I see where you’re talking about with the crack, but it’s not actually cracked. The cylinder is barely salvageable at best I think... Thoughts?

Kenho21 It looks like the head was not centered very well on the cylinder, and it also looks like the piston was low in the cylinder at top dead center, which = big squish & low compression. You should be able to wake this thing up a good bit.
