Try the normal things first, New sparkplug,fuel filter and air filter. Be sure oil is proper 15-40 wt & clean. If no improvement, Remove Carb bowl. Check for water in bowl and clean. (Carb is non re-buildable). Try Carb Spray while running. Next disconnect fuel line and mix 1/2 can of Seafoam carb cleaner in 1 gal fuel and run directly into genset.
