I don't think you'll run the generator by driving it with the flywheel, it should run with the smaller pulley. Another thing you might try, Connect the generator to a battery, you should be ok up to three dry cells/4.5volts, and get the Stirling Engine turning over in the normal direction(no flame under it), leave it running quite fast for a few minutes, then feel the end where it is normally heated, it should be quite cool, maybe even a bit frosty, mean while the cold end cooling fins should have started to warm up. In industry large motors are run this way to produce liquid gas.
