Distributor ???

8.5 distributor degrees, 17.0 crankshaft degrees, R - right hand rotation distributor.

Now, want to make it easy to start, AND get between 20 and 24 IDLE degrees? If so, shoot for 14 INITIAL and add with full vacuum, 10 crankshaft degrees for a total idle of 24 degrees.

A very simple degrees stop can be made for the vacuum advance, ask for pictures and instructions at: [email removed by staff]Totally free, no ads, just how to do it right. Yes, works on more than just GM vacuum advances.
