Even then I think it might be extra confusing to them. Apparently it ran best @ 30 total ( I actually don't remember that, and will look it up as soon as I can). They would have to hold it at 6000rpm for a longtime I bet. J.Rob
He could just keep checking it like he was……at like 2k……and keep retarding it 1-2deg at a time…….and then after zeroing in on what setting yielded the best power……..zing it up to 6k and make note of what the true total timing was.
I thought on the last pull he was at 26*, at whatever rpm he was checking it at.
