my b6000 starts all the time, never had a problem. We had some really cold temps over the past week, -10 one night, mostly single digits the others, went to start the old girl to put her to work tonight and she wouldnt start. It turns over, but wont start. If this is gelled fuel, how do i go about a remedy for this. My bota wont be the same if i have to plow the driveway with a truck.....thanks
