Re: Help decipher GM distributor vacuum canister numbers
Charkey's adjustable Mech advance modification, maked the GM distributor a very useful product for all applications. Giving the user more latitude in tuning the ignition advance. this way yiu can try different advance settings, quite easy to find the right one. However, it must work with the carburetor and AF meter. Takes alittle putzing.
