If it does have a flywheel with points behind it remove the flywheel the same way you would a larger mower type engine. here is how I would do it-
remove nut that holds on flywheel
put the nut back on just to where the top of it is flush with the shaft top, this will make a striking point for next step
put a screwdriver UNDER flywheel and pry up on it while simultaneously hitting the nut on top of the shaft. flywheel should pop off after a hit or 2. wd-40 it first. CAUTION- do NOT hit just the shaft itself, this will mess up the threads for the nut and you will never get it back on making this piece of equipment trashed. Always hit the nut that is flush with the top of the shaft. If I were you my first attempt to return fire to it would be to clean the magneto and magnet on the flywheel. Make sure it is rust free or it will not send spark to the plug.
