Chainsaw Repair

Don't worry about metric/imperial; I do both but feeler guages are in thou.

There is no window in the face of the flywheel. Even if there was, there is a metal cover over the points mechanism.

I can't just set the points because I have had the backplate off to replace the wire from the on/off switch. (not much insulation left on the wire. It could be the cause of the no start problem)

When I come to set up the make/break, there is still a circuit even with the points open; it is grounding through the coil. The coil appears fine; it is wound from the metal former, so it would ground.

To set up the points gap with the ohm meter, I would need to disconnect the coil.

The other way to do it would be with a cigaret paper between the points; rotate the back plate until the paper will just withdraw. That is the way we used to do cars with distributors.

Is the capacitor the black lump behind the spark plug?

Are sets of points available? I think the heel of the cam follower might be badly worn. This could effect the gap setting. The most imortant facor would be the make/break at 22 BTDC.

What about installing the recoil cord? Is it six turns around the pulley and an extra one to pre tension?

That'l do for now, thanks
