This may be overstating the obvious, but what about this: Check the orientation of the rocker arms? One time as a novice engine builder I accidently put mine together wrong. They are marked, but I had them flipped Intake for exhaust. This caused a rattle localized to that side of the engine. I returned to their proper order and the rattle went away.



I'll take a look at that today, thanks for the idea. I *think* I looked at that and they seemed right but I wasn't specifically looking for that. Could be a couple are out of order like you say.

Appreciate the help very much.
