I was getting no spark from the spark plug ignition wire, so I went to my local small engine repair shop for a replacement ignition module for my old Briggs equipped Snapper mower (12F802 2021E1 99062956) The mechanic there suggested I check some other things first--- file/sand off the module where the body of the module makes a ground connection and check the switch for a good connection. Anyone care to predict the odds that will solve the problem? By the way --- there is a wire connection apparently to a switch on the safety shutoff to the mower. But how does that work? I would have thought that the body of the module provided the ground, so what is that connection doing?

I just bought the 4 cycle straight shaft craftsman and it seems like it does not operate as good as the 2 cylces do. I think it (the 4 cycle) turns at less rpm's and I am not used to this. Did I buy the better or should I return it for a 2 cycle? I have to give the 4 cycle alot of gas for it to turn and cut anything.
