RE: .020" TEE-DEE Port Specs and durations
I think this is a really interesting subject, Dave. Although I have a green thumb when it comes to getting engines to run, I know next to nothing about their internal workings. I used to read all of Clarence Lee's reviews in RCM and one of the first things he seemed to check was the timing. It seems that this data really tells the true story about a given engine, more so than the metalurgy, ie., ABC, ringed, etc. But, like I said, I don't know much about engine design.
