Mtd snowblower 4.5 no spark new coil,new plug, wire is good,switch is good, new shear pin
>>The Following is a Basic Instruction File I Made for Checking the Coil/Ign Coil/Magnetron/Armature on Small Engines. Any Input is Appreciated.
>>**To Check the Ign Coil; Remove the Spark Plug/s.
>>With a Good Plug, 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 and Check the Oil Guard Switch also.**
>>If you have a New Coil/Ign Coil and Still No Spark, then
>>Turn the Coil Over and Check for Spark. Ign Coils are Wound 1 Way for Clockwise Engine and the Oposite Way for Counter Clockwise Rotation Engines. I have Seen Ign Coil Boxed Wrong and Turning the Ign Coil Over will Correct the Problem.
>>The Coil is Gapped to .015in from the Flywheel.
