I did not even know Kohler had one. I have only used the Stens one on a snowblower I fixed up for myself. Its a little Toro with a Suzuki engine. It didnt have points but it had an external trigger box. Stens has 2 of those boxes, I forget which one I used but it worked well and lists for like 15-20 bucks vs like 70 for the toro part and I wasnt sure if it was the trigger or the coil itself.Pugs, The one I have installed on the mag systems is Kohler # 25 757 10-S, Never tried the Stens type with this one in stock.
