    The motor can't backfire if it's not being cranked over! If the starter works and cranks the motor over you must mean it doesn't start and run. Did you run the carbs out of gas before it sat a long time to make sure old gas couldn't gum up the carb jets? Do you have any dirt in the gas tank?  Is the pressure bulb in the gas line staying pumped up? Will the motor run on starting fluid? If all that is good take the carb bowls off and clean the jets.
