So my son and i were hauling it through a cane field when we suddenly ran over a huge mound of soft dirt. Dirt flew up from under the seats, it was everywhere. The engine immediately cut off. The air filter was covered with dirt so i took it off and tried starting the engine. Didnt work. After a few pulls, I get a loud bang so im sure the spark and fuel is there. Does the air filter have to be on in order for it to run? What other parts do i need to clean? I looked in the carb and it looks fine.
