I just put a freshly rebuilt coil box I to my car and only the middle two coils buzz even when I swap the coils around. I know it isn't the box, so what could it be that causes this?

Roller spring not hooked up?

My roller spring wasn't hooked up, but now it is still doing it. What do you mean by an off center timer?

With the key ON - pull the hand crank until you do NOT hear any coil buzzing. Then make a momentary ground connection at each of the wire terminal ends AT THE TIMER. You should hear a different coil buzz each time you ground one of the wires there. If you do get all 4 of them to buzz then your trouble is in the timer internals. If you don't get all 4 then your trouble is in the wiring from the timer to the coil box or inside the coil box. Never start out debugging anything by saying "the trouble CAN'T be with the ......" It is OK to say "the trouble most likely is not with the....." :-)

As John says. There is a circular boss on the Timer Gear Cover that is supposed to center the timer properly. It is easy to be off a bit and that might cause your sort of problem. John's tests will find out more quickly and with confidence than moving parts around.

I traced it to a poor connection that I had overlooked. Thank you for the help!
