Check the valve clearances that's a good place to start if it still has a spark once it has cut out

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.

Seems that your carberator maybe clogged at the jets. However, before you purchase a rebuild kit for your carberator make sure the fuel flow coming out of the fuel tank has a steady flow. I have seen where the fuel hole or line at the tank becomes clogged. If you feel the the fuel flow is poor grab a wire type coat hanger and clean out the hole and fuel line. Also, check for fuel filters, replace it if you have one on the genset.

try to clean out the carb first with auto parts carb cleaner, then you may need to buy a totally new carb for the unit, as this company will NOT sell parts for these carbs due to the carb setting is sealed & has to stay at a set level for voltage output and setting

Fuel system needs cleaned. Dirt or build up get's in the passages and it can not properly regulate the fuel/air mixture. Being it runs well in choke position I would suspect it is plugged on the idle passage. Sometimes you can add a very small amount of "Seafoam" to the fuel and let it run while slowly moving the lever to the run position and this will clean it out. It is also possible that the fuel tank has a small amount of water in it. Good luck and have a great day.

I have an HM100 on a 5500 watt gen with the same problem. This motor calls for a J17 spark plug, but I found using a J19 (hotter) plug solved the problem. I think the J17 doesn't get hot enough for a complete combustion burn so it act like fuel starvation thus resulting in the black sooty and wet plug.
