For once I made the right choice. Maybe Tracy needs to add a rev limiter feature so that the engine won't run over 9000 rpm for those others that insist on doing it. Sounds like an easy software change to me. :) Anybody want to go over 9K? (Except Lynn) Bob W. On Sun, 8 Jan 2006 10:31:21 -0600 "William" wrote: > Congratulations on the first engine run, Bob.
