Andrew:
Honestly, i can't tell you. I would suggest re-checking your wiring, and maybe testing the starter. I've never had to on mine, though, so don't be asking me for pointers. I don't pretend to know anything. when the simplicities at work have done that, my first thought is always dead battery. So, i hook a battery charger up and they take right off, or at least crank.

On the 126, well, i need a new coil.. I'm holding my breath to see how much the one my boss dug up will cost me.. Brand new from Kohler is $68, so i'm hoping this one will be around $40- $45.
