I ran it Friday night and all was well until pulling up to the dock to take out . It started running rough at first on idle then died . Figuring it was out of gas as had just run about 20 miles on the river and had stated multiple times loaded it on the trailer the hard way . Before heading out put on the fresh tank of gas and tried it at home as have been down that road of not too many times before . It never even tried to start ( pull rope version ) I made a trip to town and bought new plugs as my new ones in my tackle box didn't seem to help . After putting those in still no go . Checked spark and it looked weak to me and after a couple pulls on the rope the bottom plug looked wet . I had replaced the switch box several years before and being the packrat I am saved it . After it sitting with the plugs out for a couple hours it fired once then samething drown plug . Checked fire and found good spark on one cylinder . This was why had bought a new switch box about 15 years ago . So here I sit with a motor that doesn't run and blisters on my fingers from that pull rope . I am thinking the switch box again but throwing $130 parts at it in a hope and a prayer isn't a good idea for me . Does anyone know how to check out a switch box to make sure that is what it is ? I do have a multimeter . I was told this was a 81 the serial number is 8008381 Any help is welcome as the wife is as bad as me about wanting to be on the river and anyone knows when Mama ain't happy ain't no one happy .
