One of the issues here is that we don’t know how the engine ran before you got it, or why the camp ground decided to get rid of it…Perhaps they didn’t tell you something….
I like your explanation about the module failures, makes sense to even this feeble brain.
Can you run the engine in a bucket or test tank instead of lake testing? I’m sure you want to get this thing sorted out before next season. Pulling the plug wires while running can be done in a tank at mid-speeds. Just seems like this thing is running on just one cylinder, especially considering the fouled lower plug. Don’t forget to try new plugs! Just cuz the plugs are new, doesn’t mean they are any good…
Have you pulled the carburetor core plug yet, you can do this without removing the carb to see it the metering holes are clear and to check for a damaged low speed needle.
You mentioned reeds in your last post, which is possible. While you rarely see broken reeds on these engines, but there surely could be some crud caught under one of the reed pedals. The problem here is that you must remove that pesky rewind to get the intake manifold off. So, I would hold off on pulling the manifold until you have ruled out simpler stuff….
Most of our issues are usually simple ones, until we skip over the basics…
I am experiencing somewhat similar symptoms on a 6hp that I just rejuvinated, maybe we will help each other out figuring this out….D
