Problem solved! It was the fuel shut off solenoid. Mine was mounted horizontally on carb. It wasn't clicking w/key on so I guess the stars were aligned just right last night, 'cause I tapped on it then viola, the little bugger started to work. Then she fired right up.
Thanks for all the help, hopefully I can return the favor in the future.
Now lets get the plows ready.
(If it's got boobs or a key, it's eventually gonna give you trouble!)
