Pertornix is wired in, need to run a wire back to the other side of the ballast resistor for a full 12V.. I always run the resistor with Pertronix, why put more stress on the module for no gain in performance in the range I run the engine. Installed the oil bleed back flapper, spring and tube... all I can see is it hold more oil to make a mess when I change the oil. I guess the real reason is people complained the oil light stayed on too long on cold starts because the filter drained back. Distributor cover shot with clear. I have installed many different torsion boots but this is the first from DMT... Jim knows is stuff, I installed these with my fingers! So easy! Need to installed vacuum plugs in carbs so I can balance them after I get it running. Going back to my old motorcycle days to get plugs that you thread into the carb body.
