[QUOTE="RichyRich23, post: 202435, member: 3733"] Okay so the I'll have to check everything in the flywheel area tomorrow. As for the reeds what would I be looking for if there's something wrong? I did a couple compression test the first time I got roughly 90-95, The second test was a little more concerning it was only at 60. I plan on boring the cylinder to 70 or 71 mm The spark plug is brand new so that doesn't concern me very much.. I ended up tearing the top end down today and discovered that the crank case had some gas chilling in it. also when i pulled the expansion chamber off i was surprised to find that there was gas chilling in it also. Could the float sticking open be the problem to my "flooding" issue? I've looked at the reed valve assembly and the only thing that concerns me is some reeds aren't sitting completely flush.
