seakaye12 I hooked up my timing light just to make sure I had spark on both cylinders . I had good spark on both cylinders when the motor was idling . When I turned the throttle up, there was a point when I got no spark on one cylinder.
That made me think that something electrical is breaking down as my rpms increased. This didn’t make me happy since I knew nothing about the electronic ignition or what to expect when I pulled the flywheel.I looked at the print that sears had online and found that they had these things they call transformers that looked like coils to me. I researched further and found that some people retrofit sierra coils to fit these sears transformers. At this point I was ready to quit, but I pulled these transformers and tested them with a meter like I do to coils. I found one that had no reading through the spark plug wire so I pulled the spark plug wire end off and tested directly to the bare wire and got a good reading. I installed a new end and job done. The motor runs great after all those hours of frustration. thanks so much for staying with me on this. craig
