Re: 35 GTR Sounds like a skinned spark plug wire to me. Check the rubber bushing that the wire goes through to shield it from the plastic front cowling . Sometimes they slip out and skin the wire

Re: 35 GTR Did you ever adjust your valves? I'm wondering if this is the cause of your pop you previoulsy posted and vibrations. If it misfired and then not getting a fluid current to spark that cylinder...

Re: 35 GTR With a spark plug missing by grounding out, it coulda missed a few revolutions, the unburnt fuel got into the exhaust & backfired.

Re: 35 GTR I'd check the spark plug wires and boot for any signs of chaffing. However with all the rain we have been having lately I have heard this complaint alot, and could also be a probelm with the coil (when it gets wet). Briggs changed their coils about a year ago to a fully sealed one which doesnt seem to have as many problems when they get wet.
