Dear BG tech support.
first of all thanks for responding. very nice of you.
I don't know where to set the timing. It's a custom setup of course - not factory. Big hydraulic cam in there. right now the initial timing is approximately 30 deg BTDC at idle (no vacuum advance) If I go less or more than that 30 deg number, the engine starts to have troulble staying running. the primaries are down pretty good drawing from the idle circuits not the transfer circuits (did that last year before the rebuild) the secondaries are cracked open to allow a leaner mixture (but they may have to be cracked more) I will play with the mixture screws next time I run the motor and test them as you say. I am looking to get the normal 600-700 RPM at idle when the car is in gear. Is that ok? Someone mentioned to me to check the power valve on the Holley carb. what are your thoughts?
