1050
Well, mystery solved I guess.
With fresh fuel, the idle is back to normal. Reach inside, turn the key, and it starts up without touching the pedal.
I think I know why too, now.
The 5 gallon jug I got the old fuel out of, had the oring for the cap laying in the bottom of the jug when I went to refill it this week. Maybe it wasn't really sealed and all the light ends of the fuel evaporated.
Thanks for the suggestions.
