rmdhawaii,

Thanks, I know the pinions are silghtly worn, but I tried again today. I put a dab of red locktite and it seem to do the trick, just hope I can loosen it now.
Maybe another factor was that when testing today, I heard a little noise high pitched, like a whistle. I stopped running, engine was still amazing. Got it home and took it apart, nothing I could see wrong inside. Then I played with the clutch. Bingo, blew the small clutchbearing apart. Now I feel a whole lot better.

Heres another question, at about what intervals are you changing the conrods. I have over a gal in it now.

Thanks
Charlie
