To really see what is going on you want a good gas analyzer / O2 meter to check that it is not leaning out. If it does you might get some detonation. Not too much of a hassle in an NA car. I know you have checked the jets, but did you check all the passages in the carby too? Like blowing them out with compressed air... If so then it must be an electrical problem. BTW the diaphragm on top of the carby is the power diaphragm, and yes both carbs should have the same jets. Becareful though incase the numbers on the jets are different, but someone may have attacked the jets with a number drill and resized both jets the same size anyway! (Read about a case like this in street machine) I know you said you have changed the leads, but did you change the coil lead too? One dud lead or dud spark plug will affect only one cylinder, the coil lead affects all cylinders. Dumb question, the coil was never dropped or struck across the top. It only takes a hairline crack down the tip of the coil to stuff it. Presuming you checked points gap, rotor condition and dizzy cap too? Have you checked for arcing inside the cap? Usually given away by a fine dark line between electrodes in the cap. I don't know, maybe your cap is new... Kinda hard with out looking at it [Report message to a moderator]
