Yes, very confusing indeed.
I just want to mention something about a test you recently performed. You mentioned that the engine picked up RPM as it ran out of gas with the fuel valve off. You concluded that the fuel system is somehow flooding just one cylinder and the affected cylinder begins to fire again as the fuel runs out which resolves the flooding problem.
Perhaps this is the case, but I am going to doubt your conclusion a bit. It is normal for most engines to pick up RPM as they run out of fuel as the fuel system/crankcase leans out. So, I just don’t want you to go down a bad path based on your conclusion. Indeed, you conclusion may be possible, but unlikely. Again, you have stated that your engine does NOT have an auxiliary tank/fuel pump set up. Your theory would have more validity if your engine had a leaky fuel pump that was flooding just one cylinder. I suppose the engine could have a primary/crankcase compression problem that could create a rich condition on just one cylinder, but this is unlikely, and you have mentioned that your compression gage readings are good.
I will spend some time re-reading your posts, but I fear we are missing something basic here.
