Dual Point gap setting??

Just rotate it and check for valve spring coil bind and retainer clearance. Good luck

Looks like we're in for some icy precipitation tonight.

Yep. Weather sux. Got to go to Atco on Friday to help out some friends. Great end of season day!

I'm thinking it may have something to do with the 17-year old driver that was in the car when it started "popping". He swears that he did nothing to hurt it. That's what I would have said as well. LOL. I guess God has a sense of humor...and a long memory.

Other then old valve springs I think you found your problem. Bet you didn't know that engine could rev to 8,000 rpm when you weren't looking. LOL.
