I have a Chinese 2hp on the Coleman Generator. It is OHV (Over Head Valve) and since the windings are worn, but I replaced the capacitor it just does not still do to well. The mechanical governor works, but sometime just all of a sudden it just stalls and it has to sit for a long while before it starts again. I think it is the rusty tank. Cleaning the carb showed that it is just an ongoing thing. Also the magneto had to be changed as the guy that gave it to me freebe, started it after like 50 pulls on the recoil. So that is no more with the new mag. Maybe though on a bike I start another with a plastic gas tank like on my current build, no rust. 2hp isn't much though, so maybe another plastic tank and hook it up to an older but perfectly good alternator and battery setup. I have 90 amp one around.It is the one from a 94 Ford Ranger. It was just the brushes were noisy as one was cracked. They make you buy a regulator with the brushes, sort of a rip. If you can spot weld a new brush from somewhere you could fix it. I just swapped out the whole alternator and kept the core for a long trip and a new reg with brushes, I could be on my way without going to a garage. Briggs though, for me has been so reliable. So maybe behind my bike in a wagon I have 90 amps 12vdc running a parabolic mirror and some carbon arc lamp. People at night trying to find where the light is coming from never find it as I'm mobile. OK not legal on my OHV (Off Highway Vehicle) trail bike for one.......
OK found edit. This gen is the kind that is the brushless type, but still there are the 4 doides, maybe they leak or short once in a while and it auto stops, or too much load?
