  Matthew JohnsonAug 17, 2025
  If your Ford Inverter's engine won't start, shuts down, or runs rough, there are several potential causes. First, ensure the 3-in-1 switch is set to “CHOKE” and then pull the recoil starter. Other possible solutions include cleaning or replacing a dirty air filter or clogged fuel filter, replacing stale or low fuel, reconnecting a disconnected spark plug wire, or cleaning/replacing a bad spark plug. Also, consider draining the fuel tank and replacing the fuel if there's water in it, turning off the choke if the engine is overchoking, adding oil if the oil level is low, or waiting 5 minutes and recranking the engine if it has flooded.
