Rough Runner

[Dan201]

Here is the thing the car runs rough unless you get the revs fairly high It is a slant 6 225 from 74 I have checked and changed the timing (TDC) Plugs (fairly black but car had a rich carb) Changed carb, Fuel mixture, Choke, Plugs, Cap Rotor, Coil, Ignition control module, Ballast resistor, Wiring, vacuum advance the car is running like it a 4 cylinder and I can remover either spark plug wire 1 3 or 4 without making a difference warm or cold it runs the same but once it is warm sometimes it levels out a bit and then goes rough again I had the car running perfect until I had an accident then after pulling the motor and swapping the ICM, Carb, Battery, Alternator, Ballast to my other car so my wife could still drive now this. Also either there is something wrong with my timing light or every 5 or 6 time the plugs fire there is a miss might be my light its old also seems if you pull the wire off the plug and hold it close to the plug it runs better then being clipped on. Any possibility it could be low floats? I really don't want to yank everything off the good running car to find out in case something goes bad there Thanks

Electronic ignition, Compression was good before the accident but I will find my gauge and check again, Carb was just rebuilt so unless the floats are too low I can't see it being the problem was properly cleaned out in a parts washer one piece at a time
