Re: Magneto 610906 replacement
Thanks for the reply: The stamped numbers on the engine cowl are 143-672022 ser 7055E. The tractor model is 917.253150. I hope you don't need more info, it's at a relative's house, a 3 hour drive away!! He saved the orig-o owner's manual, and I believe he bought it around 1975 or so. It's a Craftsman machine, and the manual diagram has the subject part #. He has an old receipt from Sears for an identical coil he replaced before, their complete part # was 71-143-610906, which he bought in 2005 from a local Sears outlet (back in the day when they were still in business). I'm sure the unit is faulty, no spark at the plug end (with screwdriver stuck in there, spin the engine), pickup surfaces clean and gapped to about 8 thou, grounds intact, no 'kill switch' affecting it.
I realize they don't make this anymore, and it appears only old used parts pulled off another carcass are for sale, but I was curious if anybody out there has discovered that, say, a magneto part #XXXXX off a Troy-Built will fit if another mounting hole is drilled, or something creative like that.....I've tried (in the past) taking failed magneto-coils apart to see if I could fix them somehow, but end up destroying them even further in the process./Scott
