Is there a proper test for the dizzy vac adv unit? i.e., how many pounds vac and how long should it hold. Also, what about the retard side; the same?

Do you want to check advance curve spec.'s or just vacuum test/spec.'s?
unfortunately, gone are the days when you could go down to a good shop and have your distributor's degree map checked and adjusted on a sun distributor spin machine. You are lucky to find one in existance and then finding someone who knows what it is or how to work it is even more rare! Nuff' ramble. Anyone have advance charts for the different 914 distributors? Capn' Krusty, any input??? |
