"Mike, let's just give up and quit giving reasoned answers with facts and figures to back them up!"
Go ahead and give up... Ive asked for input on what actual timing everyone is running as measured by timing light... I get innuendos about my abilities, feedback on accuracy and inaccuracy of methods to set timing, I should check distributor condition, and now your opinion that you are banging your head against the wall responding to valid questions..
as far as facts and figures... I don't see any from HRL - just the same "1 degree over advanced causes as much power loss as 5 degrees retarded"... read that 1000 times in my post searches... maybe you can explain how you set timing in your circle track days... about as relevant as the rest of your responses.
