The only tool we had at the time for measuing the spring force was meant for use on the 4 cyl. mags, and the direction of rotation was counter to that of the 4 cyl. mags. Since then I have obtained a different style of gauge that can measure either style. However, I always formed the springs on the Phelon points to exhibit the most cosed-points pressure, and saturated the lube felt with pure bees wax in order to limit camfollower wear. Unlike the Bendix-Scintilla mags that worked best with .009" point gap, the Phelons worked best with .018 to 020" gap. Just like the book says. R.T.
