    It should run OK with just the flywheel

    You have experienced one of the things they do to make things cheaper. They rely on the blades to act as a flywheel. While the engine does have a flywheel, it is probably a very minimal one, made from aluminum and the only reason they put it on was so that there would be a place to put the magnet for the magneto.

    One good way to add the necessary “flywheel” would be to find a large diameter pulley that would fit the shaft. Finding something like this will make the job simple. If you were to try to make something yourself, you would need a way to balance it, otherwise the vibration would be horrible. A manufactured pulley would aready be balanced.
