One of the biggest problems with really old saws is the magneto coil has fallen apart or shorted out. Finding a replacement coil for a Bendix-Scintilla can be nearly impossible.
Mall coil gone south.
Remington fallen apart.
Just happens there is a common Wico coil that can be swapped in. It has a 3/8" square center that fits on the Bendix pole piece. I found one on a Homelite XL-101 and another on a Remington SL-9. The points lead and ground are on the 'wrong' end but you can work around that.
Wico coil in center of pic., a Phelon coil on left. The Phelon coil center if 3/8" x 15/32". You would need to shim to center it.
Strip off the old coil from the pole piece (I used a MFH and a sharp chizel) and grind down the rivit on one end. Do not remove the rivit or let the laminations seperate! A couple trial fits in the Wico coil will give you an indication if you got it down far enuff. File, sand and polish the pole piece smooth so it won't pick up or tear plastic when you press it in the Wico coil. Give the pole and other laminations a coat of spar varnish and let it all dry.

Press the pole into the coil and add pigtails to the ground and points lead.
