Brass Feeler Gauge

[charles]

I was resetting the ignition module to flywheel gap on one of my SXL AOs and all the business cards in my possession were miking 

all over the place in thickness .  None were exactly 0.015" .  Looking in my McMaster-Carr catalog , I found they stock feeler 

gauge stock in multiple materials and thicknesses .  I ordered brass 0.015" in 1/2" x 12' strips and be here tomorrow !

 Some models call for less clearance between the Module/Coil and Flywheel than .015".

 I have an old USA made  Challenger-06BR  five blade brass feeler gauge set that ranges from .004 - .012".

Not to derail the topic but why is it important to be brass?

Brass is not magnetic so it won't stick to the rotor magnets.

I’ll have to double check next time I’m at the shop but I believe my HF feeler set has a brass (or something non ferrous) .015 gauge

Kinda old thread but just my 2 cents worth:

Some Automotive feeler gauges have a .010 brass feeler buried in the middle, but I most generally set gap at .012 and don't mind the gauges being magnetic when doing magneto laminations legs air gap I pull the magneto all the way back and lightly secure, sometimes stick two feeler gauges to the magnets at the lamination legs loosen the magneto mounting and let the flywheel magnets pull in the magneto and the metal feeler gauges stay in place on the magnets.

If I need non-magnetic elsewhere for setting air gaps I can use my dial caliper or mics and find pieces of flat plastic from containers most any size and just cut what I need.

Now these plastic containers I'm referring to are made from oily fossil fuels and will soon be obsolete since Joe (Let's Go Brandon) does not like fossil fuels, so get what you need fast, anything made from fossil fuels is going extinct the way of dinosaur eggs.
