THe highest I can find is a 11R advance.

You can lengthen the slot in the arm that limits the travel in and out of the pot, with carefull work from a Dremel tool and a cut off disk, and make it any amount you want. Measure the slot, and do some match to figure a proportional amount to lengthen it. Simply slice a little metal out of the arm to lengthen the narrow part a MM or two, what ever the math tells you.

what is the formula to determine how much to cut out? thanks

If L1 is the current length and A1 is the current advance let L2 be the new length needed and A2 the desired advance then the formula will be:

L2 = L1 X A2 / A1, assuming a linear relationship.

thanks!

That tach deal concerns me. Most I've hooked up have had the following wires. Black - earth/ground, Red - positive/hot wire, White - dash lights, Green - trigger wire hooks to neg side of coil.

Hope that helps.
