A-4 poops its pants...

Just got back from a spectacular sail... However... shortly after leaving the dock, my A-4 starts making a "pinging" noise. The power quickly faded, but I kept going for another mile, as the conditions were just too nice. Had a spectacular sail out to the Atlantic, turned around, then fired up the A-4 about a mile from the dock. The pinging was still there, and it starts smoking after about 15 minutes of running. I added some Marvel Mystery Oil, which didn't do a damn thing. Temp was normal (158F, approx.), oil pressure normal. We made it home, but something is definitely wrong here. I haven't had time to look into it, but was wondering if anyone cared to hazard a guess...

Thanks, everyone.

Check your compression first. I would guess you have a piston problem. On second thought, if you have a bad piston you should have a lot of blow-by in the crankcase. Pull the oil cap off and watch for pulsing pressure while running.
John,
Thanks for the response... I'll do as you recommend and see what's going on. If it's a pistol problem, I would imagine that it will require pulling the engine. Probably shouldn't get ahead of myself here...
Thanks again.

If it is a pistol problem there could be real trouble. We don't want any excuses for gun control.:laugher
Jacky,
Is Wayne LaPierre a good A-4 mechanic?
I don't know if it is an air intake issue he can add some holes
Try replacing the points and condenser.
