The other thing that could be giving you problems is the coil and they are a bit hard to find as well but as your other motor has spark you can take the coil, points and condenser from that motor, just means you have to remove both fan wheels . Only problem with doing that is unless the fan wheels have been pulled off before you are going to have to tap a 1/4 inch whit thread into the 3 blind holes for the puller to bolt to. This is going to be a steep learning curve for a 16 year old to get your head around but anything you learn from working on this mower will stay with you for life
