I checked the timing on the mags and the points open correctly set at -5 deg ATDC (these are M9-35 mags with 36 deg built in timing). I noted that the left cap had arcing and a lot of carbon. A problem that I see is that when the mag is timed to fire the #4 plug points opening, the rotor is still 10 degs BEFORE the #4 wire position in the cap (I'm guessing this explains the arcing). The right mag is correctly positioned so the points open AND the rotor points to the #4 plug. Note this is the single finger rotor with the slick start energizing the P-lead, not the booster coil and dual finger rotor setup. Assuming the above is not correct, how do you adjust the rotor postion on these mags? It seems that I need to KEEP the cam that the points ride on in the same spot, but shift the rotor. I noted an adjustment on the lower "bar" that inserts into the rubber drive block, but I think that will adjust both the cam and the rotor position. Please email me directly as I only get the digest.
