Did it do this before you changed plugs, dist cap/rotor, carb???????


If it has only done it since you changed plugs, cap/rotor--------check out the order of the plug wires--not only at the cap, but in the proper order and location-It is not unusual for a novice to mix up some or all of the wires-can be just a couple switched, all put on cap starting wrong place, wrong rotation. Chev common to have # 1 & 2 mixed-also at plugs easy to cross wires as each pair on a small block are equal

Another way to say that is that it's not unusual for an experienced mechanic to mix up the wires, either on the cap or at the plugs..... It never hurts to check for the easy things.

Another thought, what brand plugs did you put in? Many today are made in China sweat shops, and it's not uncommon to get a bad one (or more) in a set. AC is one that used to be top quality, but have seen problems in recent years. I use NGK's now. Same on the new cap? Accel is one that has seen more than it's share of crappy parts, to the point that many won't trust anything with their name on it any longer. Again, just a thought, just trying to help.
