Powermate plus 1750 portable generator. Has fresh gas, will just runs a couple of seconds on starter fluid and just stops.

Put an inverter on in.

It's almost certainly gummed up gas in the carburetor. Get some carb cleaner, and some spray instant start. Drain the gas from the tank and put a small amount of 50/50 carb cleaner and gas in the tank. Remove the air cleaner, open the choke, spray a little instant start into the carb and start it. It may fire just a couple of time. Keep the choke on to try to pull a bit of gas through the carb. You may have to do this a few times. Once you can tell some gas is flowing, open the choke slowly to keep it running until you use up the 50/50 mix. Then try a small amount of straight gas in the tank to be sure it works right, before you refill the tank. Make sure you use a stabilizing additive in any gas that you store for more than a month. good luck, Al K

if you are running the engine at full CHOKE, then it is flooding the engine, but if you meant off full choke, then the carb is still stopped up. Try soaking in carb cleaner overnight after removing jet & all rubber goods. HOPE THIS HELPS.

You problem is likely either low on oil, a bad oil sensor, grounded (shorted) ignition circuit, or a misadjusted or bad magneto coil

Engine speed is low, does your meter read frequency? Set for 60 Hz @ speed. I doubt there is a voltage regulator adjustment. This may help
