Default Re: Model B Distributor in a Model A

In my experience, rotors are never ready-to-go out of the box. If you find one that is, you just got lucky. You almost always need to tweak this clearance. By this I mean you may need to judiciously bend the end of the rotor tab either up or down to adjust the clearance. Sometimes, I have had to do some slight filing on the contacts in the distributor cap to get the 0.025" (or close to it) gap consistently on all four points. Most times on new parts, I have to do both. Make sense?
