I am asking because of my hot start problem I experienced.
I had to knock my advance back abit to ease hot starts and the strain on the motor.
I haven't really gone back and tried to bring it back up a degree at a time finding the sweet spot. But I was told about these boxes ( if u have MSD) where you can dial in advance upto 15 degrees from the drivers seat.
