    I just grounded the plug and pulled to see if there was spark. Both seem nice and blue. When I was checking the top crankshaft seal the wire broke for the top cylinder. Fixed that yesterday. I got spark on both cylinders again. I will try and see if it will spark a 1/4 inch gap this evening and then hopefully try and start it again. Thanks for all of the help.
