geep, Today there is a post on a chainsaw module where 2 responders specified .010." I suggest finding a specific spec for the make as 2 strokers (yours?) seem to have a lot of coil adjustability (from the pics)

You are using a business card thickness? Find the gap on some factory literature if possible.

gepp, In a 1999 chainsaw repair manual I looked at about 5 makes and the ignition gap was .012" to .013." If in doubt get a micrometer or caliper and search for a piece of plastic, cardboard, or brass shim stock to be sure. Three out of four called for locktite because of vibration.

Edit: A little late but...my Ryobi crank developed wear after 10 years and caused the flywheel to contact the module. Look for marks on your old one.

I had to use a 15thsnds. feeler gauge to get 0.10 thsnds. because every time i locked it up it would still close up. i agree with the loctite theory AFTER i get some spark, Is there any kind of bench test to determine if power pack is defective. Thanks,geppsr

You bought new? Was it in factory box? Was it used? Recently I read about good "invisible" spark. Try putting a white pc of paper behind the plug. The Briggs guys say their modules are testable on a machine, but not always so effective. You are spinning the flywheel, not just turning. It is not battery supplied so needs some rpm to generate pulse.

gepp. Sorry, I meant if there is such a thing as an (almost) invisible spark maybe a piece of white paper as a background would help you see it if there, Spin I guess should be normal pull cord speed.
