You keep say that back then you didnt know any better. What about all the advice you got back then on the Orion thead?Pages & pages,The guys told you about changing that bearing etc etc.I think YOU keep dancing around the point.I never say that is You run that engine with a overly rich lsn and run it in dirt is going to be OK.You had nothing but trouble with BOTH those orion engines.Let me put it this way,If you run a overly rich lsn for break in on a street,You are going to be ok.This is why I tell you that you can not say that general a overly rich lsn is not going to kill the front bearing...
