I recently purchased a motor off of it hate to say it ebay for my indy and I switched over all the other stuff off my engine that sucked a lung. After starting it up the clutch side cylinder is backfiring I have switched coils carbs adjusted everything I can and it still does it. If I unhook the plug it goes away with just a dead cylinder. What's the chance that the timing is off a bit or the crank is off? I ran a compression test and have 125 125 and 120. It sounds like it's coming from bottom of the engine more so than exhaust. PLEASE HELP
