The carburetor is probably clogged up. Mix a bottle of carburetor cleaner with the gas to see if that would help. Also check/replace the fuel filter.

Check your air filter to make sure it is clean, especially if the gen. has been run in dirty, dusty conditions. Make sure the gas tank vent is not clogged.
Also, pour some combustion cleaner into the carb. through the air intake to clean the carb. It sounds like it is starving for gas.
Hope this helps.

With parts list in hand, look at reference #21 governor arm and reference 89/90 adjustment screw. This adjustment will increase decrease engine speed. I would use a meter with hz setting to set engine speed to achieve 60 cycles. Sixty cycles on the meter would indicate that the engine is turning 3600 rpm which is max. If all working correctly, voltage should be around 120v at 3600 rpm and 60 cycles. Good luck

Your throttle plate and or governor arm may be out of whack. Download a technical service manual in a pdf off the internet and follow the instructions on how to set them. Be sure to put a 6mm pin or bolt in the hole while adjusting. You want to set your governor arm prior to setting the throttle plate. I had the exact same issue on mine and that was the resolution. Good luck and be sure to set your rpms correctly for high and low speed idle. Again the technical service manual will provide info on how to do it all. They sell a little hour / rpm gauge on ebay or amazon for like 15 dollars where you just have to wrap the wire around the plug wire 4 to 5 times and it will read your rpms. :)
