anything is possible, but these engines are close to bullet proof. You will probably have a stuck valve or two. Will the engine turn? Is the machine still in one piece? I can walk you through alot of this if you have the time.
If the engine will turn, then with a rebuilt carb and magneto, new plugs and wires your machine should fire off. Once you get ther let me know and I can email you a wiring schematic on your machine.
