I dont think that was the problem, because it runs great and right at 215-220 with plenty of smoke one the straight the only problem I had with the engine was it was hard to strart after the engine cooled, I would have to have the throttle at wot and afte a few sec it would finally start up..
we will see what happens I am going to change the bearing and try it again, it just sucks because it is a band new engine and I have never had this problem with other engines
