With an ohm meter check resistance of ignition module primary/control wire to engine frame (spark plug shell is best). Have all connections to ignition module in place.
With run/stop in stop position the reading should be zero or near zero.
Move run/stop to run position. Resistance should be sigbificantly greater or infinite. If reading remains at zero, the stop switch is shorted or primary wire short to engine frame somewhere.
Check the ground wire on your coil and see if it is loose or well grounded...

You may need to use a jumper wire between the threaded part of the plug and the cooling fins. You do not have to bend up the electrode.
Ignition module gap
Place a business or index card between the fly wheel and coil, rotate until the magnetic attraction pulls everything tight together. Tighten the coil screws, rotate the flywheel until the attraction eases and remove the card. Ensure nothing contacts when flywheel is rotated.
