Ya, I was thinking that would b a weak link. Im Hitting them today so hopefully that will help. Now would week Reed's make it a problem like this as well? I wouldn't think so with the way it did rev when running. There was no visible damage or over wear on then when inspected. But maybe just tired, and allowing too much fuel to slip by?

 

Normally reeds aren't a problem on these engines.If seals don't help,then it's back to the new piston and cylinder you installed.

 

And I have absolutely no more compression then I'd did with the originals...Not a pound. So although I'm confident in the top end being air tight, guess I'm pulling it out/ and apart...Again. the only thing I can think of is maybe mixing up the top and bottom rings on the piston. I do remember now looking at them and seeing them both with the exact same markings in the same Spot. Which did I found odd. As I know the top has to b marked and installed properly. But if that's the case, why would both be marked and spelled the same..? Man I hate this machine.
