If the Engine idles roughly, unevenly, or surges.
Possible causes:
1. Carburetor is dirty.
2. Air leak in carburetor or intake manifold (e.g., bad O-ring, gasket, primer).
3. Carburetor is improperly adjusted or needs service.
Or If the Engine still operates erratically, surges, and runs unevenly.
Possible causes:
1. Fuel line or fuel tank cap vent is clogged.
2. There is water in the fuel.
3. Fuel pump is defective.
4. Governor is not set properly, sticking, or binding.
5. Carburetor needs adjustment or service.
6. Loose carburetor/intake pipe resulting in vacuum leak
