Just rebuillt this motor last summer. It's been running well until recently. It intermittenly will lose a cylinder for a few minutes, then it comes back. Finally did it where I had a chance to pull the cowling and by pulling plug wires determined it's the #2 cylinder.

I'm thinking either a loose wire or a coil finally died (getting ready to check spark, etc as soon as I hit "send" on this), but looking for any other things to check in case it's something I haven't thought of.

It starts fine cold when I first put it in the water, but then gets progressively more difficult to start as a fishing trip goes on. I'm thinking it's a coil breaking down as it gets hot, but that's just a guess.

Compression is running @120 on each cylinder, fresh Champion plugs with proper gap installed 2 weeks ago, and carbs were rebuilt last September when I did the motor overhaul.

Thanks in advance!
