Just an update. Got the new rings, end gap measured .025. At least double what it should be. Anyways block is toast. Still low 70PSi. Time to look for a new block for cheap.

Thanks for the help from everyone.

Well update time. I got a parts motor. Block looked good. Cylinder measured out at 1.565. My piston and the one that came with the parts motor measured out at 1.562. Sadly my ring end gap was still .21 nearly double what it should be and I tried two different sets of rings. That has me confused. Anyways threw it all together. Got 90psi. Better than it was with my old block but not great. Got spark. Doesn’t fire. Even when squirting fuel into plug hole directly, its sort of wants to fire but doesn’t. I’ve got two of everything now, so i guess my next step is to swap the electronics even though mine are new. Maybe for some reason I’m not getting good spark under compression.

I used the gear case and lower end from the parts motor so block and lower end were from the same motor. But I applied a thin layer of gasket maker to head, let it dry for a few hours. compression tested the same (90psi). But when pulled over it really wanted to fire up this time when choked only. So that made me think fuel. Well I swapped out the carb and WELL holy crap it runs!!!! What a pain this motor has been. But hey for less than $150 Canadian dollars total I have a 2hp that I know the ins and outs of. Plus I have spare parts galore haha.

I’d like to thank everyone who has given me input and advice on this little guy. I sure learned a lot and appreciate it.
