I inherited a Mallory Dual Point in my TR3A that has been nothing but
trouble. Whoever installed it in the car in the first place located the # 1
terminal 90 degrees out (or some approximation there-of). I really need a
guy with a machine to reset this unit up. It is my best guess that since the
unit comes without a driving dog, the DPO just drilled where ever he thought
it belonged. I've pretty much had to guess at the timing, no doubt adding to
my overheating problems. I switched back to the stock unit by locking the
plates at full advance (no vacuum). Does anyone know where I can send the
Mallory, have a set of the factory instructions or any advice on running the
stock unit? I get to try it out this coming weekend.
