Ok, more?s on the timing. I put the #1 piston at TDC and when I looked at the distributor with the cap off, the hash mark on the rotor is about 7 or 8 mm past the hashmark on the distributor housing clockwise. I have the car idling well and accelerating well, but when I decelerate it has little backfire noises in the exhaust. Do you think the backfires are because its retarded, or advanced, and wich way should should i turn it to cure it, clock or counter clock. Thanks all.
