Hey guys unfortunately my stock vacuum advance diaphragm has gone bad (causing slight hesitation upon acceleration). The inner diaphragm closer to the engine is the culprit. Read this is pretty typical. Would really like to keep the oem distributor considering it works plenty fine. Wondering if anyone knows where I can find a replacement vacuum advance unit. I ordered the cheapest dizzy i could find just for the vacuum advance but the mounting screw hole doesnt match my oem distributor.

 

Do you have a user manual ?

 

What is the user manual going to do here???
