Here's my setup...'74 2056cc with new NGK plugs new wires new Accel coil and a Pertronix Ignitor.

I'm still trying to figure out what's wrong with my ignition. A little history...Two weeks ago the engine had a miss. Replaced #4 wire and it went away. One week ago, engine developed an erratic miss thru all RPM's, but car was drivable. Two or three days ago, engine is missing so bad that I can't drive it. Also have developed an occasional backfire.

This morning, started the car and it only fired on cyl. number three. Not a pleasant sound BTW. Put an old dist. cap and rotor on and swapped on some old wires and got cyls. 1 and 4 to fire sometimes (#3 fires consistantly). I was checking for spark with the timing light lead.

The #2 wire is not showing any spark at all. What is confusing me is that there is spark from the #2 wire to its terminal on the dist. cap, but no spark going thru the wire. This occurs with several different wires that I have tried on that #2 terminal. I replaced the coil and am waiting on a new cap and rotor.

I rechecked the shaft in the dizzy and it does move a little side to side. Not much, but it does move. Shouldn't the Pertronix compensate for this movement though?

Per someone's suggestion, I disconnected the tach wire and saw no change in behavior.

If you have any thoughts or words of encouragement, please send them my way.

Thanks

BTW, compression numbers are in the 150psi range.
