One or two of you may remember my 070 I got for not much. It was listed as possibly bad bearings.
It had a bit of play, so replaced them with NGKs. Then the flywheel was loose on the cam so welded it. The clutch only had 2 hoes, and Dibbs very kindly helped me out with that
THEN it wouldn't spark. Dave very kindly helped me out with a condensor. Although it proved to not be the problem, but I do have a nice new one in it now! After hours of hair pulling I found the points had a resistance to ground of a few Mohms when open. I degreased the insulation/bush on the arm and this cured it. For a few hours. Then it gave out again.
Yes I should have got new points, but not wanting to wait for a US nor willing to pay Stihl prices, I opted for another option...
Took a block of electrical insulation - hard and good with heat.
Cut a sqaure block and drilled a 4mm hole through it. Then put a screw through it that just bit, and put the screw in a drill (read lathe)
"Turned" it, with a raker file 'til it was round, and just fitted in the hole in the points.
Quite neat even if I say so
Fit it and set the gap to 0.4mm
And guess what...

Ok so it may not last years of intensive use, but it won't get that. And if/when it fails, I'll just bight the bullet and get some OEM points! But for now I haven't spent more than the sale price on it - £47. That's with a little help from Dibbs and Dave K though - thanks guys. So now I just need to spend some money on clutch cover, filter and bar stud. Then figure out how my tach works...
