Made me think of the day I was running my dozer when the fuel guy showed up. I throttled the machine down and let it idle for a while til he was ready and shut it down. We got to B S in' for a while and when it was time to get back to pushing dirt the damn thing wouldn't start!
Finally realized I had forgotten to put 'er in neutral before I shut down.
Anyway, I bet it's something simple and you'll get it figured.
p.s. what Tim said, "no ether"
