Answer
Hello Dale:

>>No Worries.
>>***Anytime a Magnet that is Set to the Correct Distance from the Armature/Ign Coil Pickups, the Armature/Ign Coil will Fire the Plug if it is Good. The Armature/Ign Coil Gap should be .020in between the Flywheel and the Armature/Ign Coil Pickups. You can Use a Side Panel from a Drink Carton (Mt Dew, Pepsi, ect) and Place it Between the Flywheel and the Armature/Ign Coil. Allow the Magnets on the Flywheel to Pull the Armature/Ign Coil Together and then Tighten the Armature/Ign Coil Bolts. Carefully Turn the Engine while Pulling the Cardboard Out from between the Armature/Ign Coil Pickups. The Armature/Ign Coil is Now Properly Set.***
>>You can View a Breakdown/IPL of this Engine at this Site Addy, http://www.outdoordistributors.com/ and Select the B. Then Select Briggs and Stratton. Then Select Don't have Part Numbers. Then Select the File #12 . Then Select the Folder #124700. **Note: you can Download and Save the Breakdown for your Engine by Selecting the 2nd Icon from the Left at the Top of the PDF page.**
