during operation (engine
RPM is fluctuating).
1. The fuel isn’t running
through the fuel valve.
2. The air filter is clogged.
3. The muffler or spark arrestor
is blocked
4. There is gunk in the carbure-
tor preventing a consistent
fuel/air mixture.
Turn off the generator and wait for it to cool down.
Perform the following steps:
1. Check if the fuel is properly and consistently going through the fuel
valve
2. Check for any blockage in the air filter. Check and clean the air filter as
necessary.
3. Check if the spark arrestor is blocked. Clean with metal brush as
necessary.
4. Use “gunk remover” spray on the carburetor jets.
