Found the left plug a light tan, that was the cold side. The right plug was black and fouling, the hot side. Wierd, huh? My compression tester is shot and my leak tester sucks. Gonna put the autolites i bought for 2.50 each. If it still fouls, i take the right carb off tomorrow. I wonder, the float pins on these carbs are very loose. Is that gosher?
