This is my first winter as an ATV owner. It's now 5 degrees in PA. i can't get the this blasted thing started. I've tried all of the manual recommendations. I took the line off of the shut off control and noticed that I couldn't get any fuel to run out. i tried all three positions (res, prime, on) to see if i could even get a trickle. The Fuel pump is working. I was able to get to gas to suck out of a cup thruought the line as I tried to start it. Could the shut off control vlave be frozen? Any suggestion? I want to get out a plow my drive and then play in this white powder.
