Well I think I found the problem!! Got out in the shop and looked every thing all over again as it layed there in parts all over my table. And quest what? I looked at the crank and son of a gun! I had left the seals on each end as I split the case<br />and the one on the bottom was in UPSIDE DOWN! The question is, would this cause the crankcase to suck air and give me only half throttle performance?
