Engine has been spitting and sputtering when throttling up. Determined that it’s running on 2 cylinders by pulling wires off and listening for change. The culprit is # 3. The engine sat for a few year so first thing I did was open the carbs and clean them out. The cylinder in firing across spark gat tester. Spark looked alittle weak but I don’t have anything to compare it to. I changed coils around and the prob stayed with #3 so coils fine. I replaced fuel pump thinking maybe it was dumping fuel into cylinder being it gets its pulse from #3. Anyone have any other suggestions. Compresson is #1 100 #2 103 #3 98
