Thanks Bill,
After reading the horror stories of engine starts without a load, I had
vowed to not even try. 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)
