Ok
I did what you guys said to do by setting the base timing at 10 degrees and with the distributor vacuum disconnected I rev the engine up to 4000 rpm I got 32 degrees of advancement. This is ok.
Then if I hook up the vacuum advance and rev the engine upto 4000 rpm I will get 50 degrees of advancement and the bobing will start.
Is this still ok?
I think something is wrong with the Vacuum advance on the distributor.
Please help I am pulling my hair out with this one.
