Distributor Question
« on: November 17, 2016 - 09:22:31 PM »
Inside my MSD distributor cap, the points are grey colored, with each
having a black spot on the edge where the spark is transfering.
Its this black spot ok, or should it not be there?

Try brushing some fine sand paper on it, if the black wipes/sands off then it is corrosion and should be cleaned up. You only want to take off the soot, not metal.

ya, its just a tiny soot point, on each point, that rubs off, so probably ok here.
But I have been desperate to find the problem, so getting really picky.
