I have tried wires, points ,condensor cap
rotor.distributor,plugs,carb rebuilt,timing
adj,alternate grounding locations non-resistor plugs. hot wiringto bypass ballast resistor
compression test(125 allcyls) I cant even think of anything else to try, I also must note that only the front 3 cyls need to be ajar (wire off the plug) the back 3 cyls run fine with the wire plugged on????
