Answer
Hello David:

The Following is a Basic Instruction File I Made for Checking the Coil/Ign Coil/Magnetron on Small Engines. Any Input is Appreciated. **To Check the Ign Coil; Remove the Spark Plug/s. Wrap a Wire Around the Threads of the Plug and Attach the Other End of the Wire to the Engine Block. Remove the Blower Housing (metal engine cover). The Wire that is Connected to the Coil/Ign Module from the Shut Off Switch needs to be Removed (unplugged) from the Coil/Ign Module. Now Check for Spark at the Plug. If Spark, then the Shut Off Switch or the Wire is Bad. If Still No Spark, then the Coil/Ign Module is Bad. If there are Safety Switches on this Unit and the Coil is Good; you Need to Check the Safety Switches for Being Bad Also.** Send me the Model Numbers Off the Unit, Please. With these I can Locate the Proper Manual and Better Assist you. 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. Have a Happy Holiday Season and May the All Mighty Bless You and Yours. Be Safe and Happy. Thanks.

Good Luck
