Do you have to reset an error code for the generator to run properly? I got a 36 code and did a complete tuneup but still getting surging and it dies after 5 to 10 minutes. Good gas flow to the carb.

Hi, Check that you have the correct spark plug fitted or fit a new one as it sounds like your plug is getting hot then shorting out.
Sometimes the magnito can do this as well. but I would start with the plug.

Replace the spark-plug, check the quality of the fuel(gas that is mixed or was stored more then three months is stale and wont fire correctly) make sure the fuel and air filter not clogged. If there is no change then your problem may be more technical, a nest may be restricting the govenor or you missed something with the carb and there still is debre causing it to stall.

Check the vent in the fuel cap to make sure its free to breath. It could be creating a vaccume in there and starveing for fuel. Maybe run it with the gas cap off and see if the problem gos away.

had the same problem with my Honda engined mower. you can't see it easily, but there is a very fine screen in the outlet of the fuel tank that gets blocked and fuel will not pass thru it fast enough to refill carb. remove tank and pour fuel in another container . Use a flexible plastic tube in the outlet or make a small wire hook to penetrate the screen,or preferably, remove it. confirm that fuel flows freely thru it, remove any debris, and reassemble. Change spark plug, add fresh fuel,and test. best of luck!!!! Ray
