Yes, it runs. The engine even runs smooth and isn't rockin' back and forth but you can hear the popping coming out of the exhaust. Starting it cold and keeping it running from 1500-2500 rpm's - I haven't let it warm up completely because the "popping" tells me there's something wrong so I hate to keep it running.
If its a plug that the gap accidently got closed, would the popping "lessen" as it warmed up??
