I have a Intermitant spark problem that leads to fouling. I have swapped coils, charged the battery, swapped wires and spark caps, pionts are dead on and .13 gapped, left side runs great all the time, right side not so much... Carbs are set alittle lean on idle, but have been gone through. I changed the condenser wires and problem still exists.. Most of the spark testing is done while running on the good cyclinder with the spark plug out as well as with the spark plug in and a timing light. Sometimes I can run 20 miles without a problem, other times I don't make it a mile before the right side drops, pops and blows as it fouls... Any advice helps? Oh and did the resistance check on the condenser that also passed as well as both coils wires and caps.
