468, 871 blower motor. MSD 6al
The last couple of times out when the engine was cold, it ran just fine as always. Ride out to the sandbar, spend a little time there, fire it up, and backfire through the carbs. Hmm. Well, I have to drive it back to the ramp. As we drive, the spark would come and go on one (don't know which) cylinder. A few minutes later, it would clear up and I could run it like I normally do. The backfire comes in the turning over, the spark loss comes as we are running. Does this sound like plug wires going bad? I'm thinking it's an errant spark, or arcing wires causing the backfire. Anyone?
