Wow, I did not expect to have to pull the engine out to replace the module. I better make really sure that is the exact problem before going to all that work.

I read in some posts about kill wires or corroded connections causing no spark issues, I do have spark on 1 side only and the engine will run

I did notice on the tiny tach when on the non firing side, I did see rpm briefly displayed, like maybe 400-600 during start and then it quit displaying as rpm increased.

any advise on how to make sure its the module would be appreciated before pulling the engine
