I’m beginning to suspect that Frank, perhaps the first time I pulled the cylinder head, some water leaked into it during removal and gave me a false positive.
It was/is behaving like a motor with water in the cylinder, but of course with the motors which do have the water leakage issues, it’s usually in both cylinders, so I am investigating further. When I ran the motor with the head off using the drill gun, I did so for several minutes, stopping every 30 seconds or so to wipe down the bottom cylinder of fuel mix (the carb still had fuel in it from when I shut it down.
Once I got it to the point where I didn’t see signficant accumulation, I put the cylinder head back on and ran it with the drill gun. Pulled the head and didn’t see any water in the bottom cylinder, but just some more fuel mix. Top cylinder has remained "dry" throughout this whole process. The motor has been in the barrel and pumps water whenever I use the drill gun so I know water flow is occurring as it should.
Trying to figure out how just the bottom cylinder would be loading up. Either there’s some sort of ignition issue on cylinder 2 I’m missing, or it’s a fuel issue. More investigating to follow…
