Thanks gents:
NOW i have something to look for!
I just didn't know where to begin.
Doc Reiss came up yesterday to our field
and mentioned he once had one of these older
OS engines, and he said the bearing design
was just a bit minimal. Hence the WC with
a bigger main crank set.
I am using 30% wildcat w/ 18% oil, and perhaps
this is fighting the pipe. (Upswept header, hot dog
type w/ silicone coupler.) Cul, we may be low on oil
according to your suggestion.
The ring idea is good, but it bugs me that this engine
is almost brand new, heck, I was really just breaking
her in! (But indeed, low 18% oil could have caused
too much immediate ring wear.)
We have one more nice day pred@65º here in NE today
so I hope the 15% nitro will work B4 I pull the engine
as the weather turns winter outside!
Any other ideas? Thanks a bunch! Better than encyclopedia UR!
