Most have a main jet that the faster its run more it sucks fuel through, compensating is like a tank with a leak in it and runs into a bowl no matter how much fuel is sucked the bowl will only give whats running into it and no more, then there is a slow running jet with a adjustable air bypass to give ideal idling characteristics, this carb comes fixed with no adjustment, the old one is adjustable, it seems to me the compensating is to large and main is small giving a over rich at low speed and weak at full speed causing the exhaust to get very hot.
