Hi all, first post here. I’ve been chasing this for a while and it’s got me and all my small engine guru friends stumped. Few years ago, I bought a used Ariens tractor, made by Husqvarna. 42” hydrostatic drive 20hp BS single. Used it for a season, covered it for the winter and fired it up in spring. Cut the lawn once, then it wouldn’t start. No spark. Buddy put another coil in it and it ran. Cut the lawn twice and, you guessed it, no spark, and the motor would not crank past the compression stroke. We went round and round with it, three different people tried their hand at it. No go. Finally my buddy changed the motor to a 19hp BS he had on his shelf. I helped install it and it fired right up. Took it home and cut the lawn once and, again no spark. In disgust I covered it and pushed it under the deck. So here it is, spring in Maine. So I pulled it out again, got another coil and installed it. It runs! Cut the grass and no spark. I know the wiring been chopped up, all the safety switches removed, but I can’t figure it out. Help?
Clue: it’s always not re-started, that is seems after shutting it off, the coil dies. Should I try disconnecting the wires in kill switch and try a stand alone kill switch to the chassis ?
