Re: [AMC-list] Caspers Motor finding knock- Sea Foam saved my day!

Sounds like they're fine once everything is properly oiled and up to
temperature. After startup some parts are warmer than others and they don't
match up as well as one would like. 

I've heard similar things about aero engines like the R-4360. They would be fine
when shutdown but would have a problem when restarted.
