Small Engines (Lawn Mowers, etc.): Craftsmen Weedwacker Module Installation, air gap, mt dew

Question
I have a Sears Weedwackerr 17' Trimmer, Model #358 79557-1.
The spark plug was cut by the plastic housing.  I was only able to replace this wire as part of an ignition module assembly from Sears parts store.  I received and installed the module but was not given the air gap spec.  Even with the correct spec I am not sure of the accuracy because the mounting area for the module flexes and is stabilized by the case after installation.  The flexing doe change the gap between the flywheel and module.  Please help me with installation instructions.  I can not get a spark from the new module by guessing at the air gap.   Thank you Marie

Hello Marie:

The Following is an Instruction File I Made to Replace the Ign Coil/Ign Module. **Using the Provided Site Addy, Locate the Breakdown for the Engine to Assist you in Doing this Repair if you Require it. The Coil to Flywheel Gap is .015in - .020in. Remove the Blower Housing (metal engine cover). Under this you will See the Ign Coil (has the Lead to the Plug Attached to it. Unplug and Unbolt the Ign Coil and Remove the Coil. Use a Section of a Soft Drink Carton (example: a Mt Dew 24 pk Side Panel Cut to 3" x 6"). Turn the Flywheel so the Magnet is Facing the Ign Coil and Place the Cardboard Section Between the Ign Coil and the Magnet. Let the Magnet Pull the Ign Coil to the Flywheel and then Tighten the Ign Coil Mounting Bolts. Turn the Flywheel and Pull the Cardboard Panel at the Same Time and Remove the Panel from between the Flywheel and the Ign Coil. Connect the Wire/s to the Ign Coil. Replace the Blower Housing and Any Other Hardware you Removed to Remove the Blower Housing. Attact the Plug Lead to the Spark Plug. Now Start the Engine.** If you Hit a Snag or this Does Not Correct the Problem,  I am Here if You Require More Assistance. Hope this Helps. Let me Know What Happens, Please. May the All Mighty Bless You and Yours. Thanks.

Good Luck
