coil clearance?

[cobbler]

I'm putting a new coil on my Stihl 011 and wonder what the clearance should be between the coil and the flywheel? Is there a specified clearance or do you just fit it by feel? Thanks, Cobble

No no, can't do it by feel. Assuming you don't have a gap guage tool heres what will work. Take a regular pack of matches and rip off the cover. Push the coil back away from the flywheel and slightly tighten it down. Rotate the flywheel until the magnets on it line up with the arms on the coil. Slip the match book cover between the coil arms and the flywheel magnets. Loosen up the coil and the magnets on the flywheel will draw the coil to it, other words make it press againist the match book cover. Once the press is made tighten the coil down, rotate the flywheel on around and remove the matchbook cover. Your set to go. It may not be exact but its well within range to run ok.

NO matches............Index card.

Thanks all

Have a feeler gage but heck I've got some old playing cards too!

Ralph - Life got around to normal this weekend so I got back to the coil you sent me. It's producing a little spark. Let you know how this works out. Thanks, Tom

Cobbler welcome to Arborist Site BTW!!!!!!

I use a service ticket that we write up problems on when a piece of equipment comes in. Like Thall said it should be that you have to turn the flywheel to get it out,,,,

Business cards, playing cards, matchbooks are all non magnetic and compressible. In other words, easier to get out and not booger something up.

These guys is smaahrt.
