I always run my 8N with the fuel valve full open. About 2 weeks ago, my 8N started right up as usual, but shortly stalled and refused to start. After multiple attempts to start, the starter motor was acting strange. It was then I noticed two liquid phases in the sediment bowl. I drained the gas from the tank and carburetor and when I removed the sediment bowl from the tank the bulk of the water came out. It was at least a quart. With a new starter and fresh nonethanol gas it starts immediately, BUT is acting strange. Under load, the engine almost dies, Then the governor kicks in and saves it. I cleaned the screen at the carb inlet and there is good flow out of the carb drain. Would sugar in the gas cause such a problem? The tractor responded perfectly to loads in the past, so what has changed? I guess I now have to disassemble the carburetor and see what's in it.
