If you have a dwell tach, the proper dwell is 50 degrees plus or minus two at 1500rpm. If you're too cheap to buy a dwell tach, set it at 0.016" and call it good. On my car, 50 degrees of dwell equals .009" gap. Dwell is the length of time, in degrees of crankshaft rotation, the points are open. Too little dwell and you're not getting spark long enough to properly burn the fuel. Too much dwell and you're just screwing up your plugs for no reason.
Dist. Points gap is .016" (0.4mm)
