My carbs and timing were set by my engine builder, local guy who has lots of experience with these engines so I'd be real surprised if it were one of those out of whack.

I can't say yet what my topend details are because I'm still about 45 miles short of my 100 mile break in on that ring/pinion. I'm gonna try to get through that tomorrow with a couple drives with complete cool down in between, then I'll see what's what.
