Original ignition coil fails when motor heats it up. Somehow, I managed to lose one of the black non-metallic spacers that position the magneto.
Oddly, I've heard them called insulators, as in NOT grounding the coil???

>>QUESTION: Can I replace missing spacer with equal thickness of metal washers, or, do I drive across town to the Stihl dealer, because I need to keep it all OEM?

Which are you are referring to?

Item 14 just under the screw head or is it item 9?

Item 9 would be a heat insulator and they just use plastic washers in place of it.
 
THANKS! It's #9, and on my blower, it's one plastic washer between coil and engine for each bolt. I was going to head over to the Stihl dealer this morning, since last coil died when heated, but if I can just use heat resistant plastic.

Now I'm wondering why they didn't make the washers much wider to help insulate the coil, or, put a band of insulating and reflective material behind the coil. Was it 10-cents more in labor & materials?, or literally Engineered to Fail?
