    Nope. These saws were one-offs, they weren't even produced a full year before being recalled, hence few replacement parts ever made it to market. They supposedly produced 10,000 or so, and recalled most of them back because of the possibility of runaway throttle.

    Lol, got sidetracked. I'll go out to the shop in a bit and get some pics. Keep in mind, these parts aren't clean yet

    That's why we sometimes weld them.

    Mark may be able to help you out, but I don't have a single spare part for mine. If you need a part for casting model, I could help you out there.

    Mag Craft, here's pics of the parts I need repaired....

    Small chip out of side cover needs welded and sanded flush...

    Fine crack in backside of fuel tank needs welded. It leaks fluid. Non cosmetic.
    Screenshot_2016-11-20-12-09-42-1.png

    Chunk missing from back corner of bottom piston chamber/case. Merely for cosmetics. I'll make the replacement piece, it will just need welded.
    Screenshot_2016-11-20-12-09-46-1.png

    Worst part of all is the bottom handle mount on the gear case. The entire chunk is missing and will basically have to be built back up by layers of weld. There is also a crack associated with this missing piece and gear case oil leaks out of it. We'll probably have to open up the crack with a die grinder to clean it good so we can weld it. You can see brown epoxy from an old repair

    This saw hasn't ran in at least 40 years, maybe longer. I bought it out of California, where I believe it was found in a junkpile. So I don't expect miracles, let me know if you think repair is possible. I will media blast all parts that need repaired prior to sending them out.

    Thank you sir, I'll do that. Probably won't be til after the first of the year.

    Do me a favor, keep an eye out for a carburetor. I think mine will function, but it's really rough inside......

    Will do. The carb on mine is likely not much better than yours, it's running on only one diaphragm.

    Mark and I ran ours two years ago at the IA gtg:

    The bottom piston chamber case. Is that magnesium or aluminum.
