So today my husband was trying to fix my overheating issue now. We get a spark from the spark plug but it sounds like shes wants to fire up we have it sounding like its back firing from the exause and we put a new battery on it was running a few hours ago but now when he drained the coolant from under the radiator it stopped. And he has been drying the carb and its wet. Still please help me 😢😢
