    How do I get this cover off? I've taken all the screws around the outside edge out and the 2 "peddles" but it seems like there is something under the "points" section holding it on. I've got a shop manual coming in the mail but it's going to take a while to get here.

    Good morning, I assume that you removed the shift lever and kick start lever? Remove the center bolt from the points area and the two bolts on either side. Use a rubber hammer to gently tap around the case. There should be a gasket, and due to the age is probably just stuck firm to the cover. Try setting it up on edge and gently tap down and out a bit. Be patient and keep at it. Maybe try a little heat from a heat gun too. Good luck.

    Thank you so much for your help!!! How would one remove the center nut? It turns the engine over when I put a wrench in it. How do I brace it without wrecking something?

    As you have worked out you have to stop the engine from turning to undo that nut. How you do it depends on how far you are going to strip the engine down.
    I completely dismantled a Cub engine some years ago and when I got to this nut I had already removed the head and barrel. I locked the engine by placing 2 wooden battens underneath the piston skirt so that it would lock against them when I turned the nut. Once the engine was locked the nut comes undone without too much drama.

    Wood, being softer than the piston is unlikely to cause damage to the piston skirt.

    Best of luck!

    Bracing the motor from turning is the way to do it. You will most likely need an impact wrench to do this with. The impact wrench alone will probably do the trick.

    That worked great thank you again for your help. Unfortunately right under those pieces there is another thing with moving parts still holding the cover plate on that I can't figure out how to remove and I'm hoping again you our someone has some knowledge to share?

    Don't know if it is the same as my old BSA B25 was but it looks like an advance/retard unit for the points. Is there a large thread inside you can put a bolt into by a few threads, if so, waggle the bolt round, the adv/ retard is probably held on a taper. By the sound if things you definitely need a manual or you may end up doing more damage. Good luck.
