Try running the engine on Propane. Take the flame nozzle off a Propane torch, attach a length of rubber fuel line to the tube where the flame nozzle was removed, and attach the other end of the tube to the windshield wiper hose nipple in the intake manifold. Turn the gas valve on a little and crank the engine. If carburetion is a problem the engine should start and run.
