If it is backfiring the timing is set incorrectly or the spark plug wires are not connected in the correct order.
Do a proper diagnosis to figure out the cause of the misfire, then repair it.
Back fire can be caused by improper ignition or the wrong fuel air mixture. With the engine off remove the air cleaner and look below it. If there is fuel in the pipe then the carburetor is not stopping the flow of fuel and it needs a rebuild.
