'69 GTO with Isky Cam (P/N 901271), Edelbrock manifold & 750 carb. Timing @ 9 deg BTDC. Vac advance attached to carb "timed vacuum port". Engine fires & "tries" to start but quits when starter disengages. Valve lash was set by tightening ball retainer nuts to 20 ft-lbs. Stock push rods & rockers, Isky recommended springs. Sometimes backfires while trying to start. Can't figure out whats wrong. Need suggestions.
P.S. Both Isky & Edelbrock not helpful. |

It sounds to me that you've installed your distributor off 180. Or your plug wires were installed wrong(1-8-4-3-6-5-7-2, counter-clockwise rotation).

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
