Air gap

[John Wagstaff]

Morning guy's, has anybody any idea as to the air gap setting between the flywheel and ignition module for a Stihl 017 chainsaw, later model just prior to the MS170 saw.
Any info please, thanks John.

Basic business card usually gets it close enough for "horseshoes and hand grenades"

I've been using business cards and appointment cards for 50 yrs. I've never had a problem doing it this way.

Let the magnet in the flywheel pull the coil against the card and then tighten down the coil.

Works every time for me with the card

I use a business card but have folded a piece of paper a few times when i couldnt findn one. Havent ever looked a spec up but imagine it would be between .015-.025 or so. Correct menif im wrong please.

My dad taught me to use folded newspaper, was always wondering what difference it would make if its slightly far or close than given spec ?

Spark May just be a little weaker or not work. Just make sure to turn it over by hand to make sure flywheel doesn't hit the coil

.010-.012".....yep, I use s business card for every one I set.

It's easier than deeper gauges

 

[Brian Carlson]

feeler gauges I mean lol

Yea i built.a husky 55 and was so pissed cause i wasnt getti g spark.......sure enough gap was to big. Figuring that kind of thing out really just makes you want to slap yourself lol. Bit at the same time makes you feel like a boss for figuring it out

Business card works perfect on my 017. Never had any issues with using one.

If you get one of the transparent plastic boxes that they use in supermarkets for cake/cookies, usually the lid is smooth, & most are in the 10/12thou thickness range. I cut strips about 4 x 1 inch & use in the same way as the business card. Has a advantage in that you can see through it to line up the magnets + you get about 6 out of a box lid, useful as I always seem to lose/mislay the one I used last.

What a superb idea, raided the fridge, stole the lid of the Wife's cream cakes, cut to the required sizes, PERFECT. I will use this in future. Thanks for the advice.
