thanks. so i've set up the distributor so that the rotor is spot-on pointing toward cyl#1. since the rotor turns counterclockwise, would it make sense to advance the spark a little before 0 deg ? That would mean turning the distributor a little clockwise. that way it isn't exactly at 0 deg when I first fire it. it would be advanced a bit. What is a good deg setting to start with for a lightly mod engine, 5 BTDC, 10 BTDC?
