Hi -
I'm sort of new to snow areas and never had to leave a mower or snowblower sitting for half a year. Before I put either away for the year I drain the gas and run the motor repeatedly until it won't start anymore trying to get as much gas out as possible. But does anyone use STP gas treatment in something like a 4-cycle snowblower motor when breaking it out to take care of varnish/gumming problems for the small amounts of gas that probably got left behind?
