I've got my new PerTronix dist and I'm stumped on how to choose the correct springs/advance limiters for my application. to set the advance curve I'm to use one of the three sets of included springs.much like the msd.gives me a chart on the springs and where they will put all my timing in @said rpm/crank degrees.it also includes advance limiters as well.much like the msd had the bushings.distributor comes with three different sets of advance limiters. These allow the maximum mechanical advance to be limited to 20, 16 or 12 degrees. my question is,what info do i need to figure out which springs/advance limit to choose?thanks for the help.
