I am finding with a lot of these newer machines - snowblowers, generators , etc, - with the one size fits all carburetor settings that if you do not buy a machine in your own locale, the carburetor does not seem to be set correctly. Too lean for Canadian winters in other words. Bought a couple used Champion Power Product inverter generators that start first pull in the Summer but the only way they will start at all in cold weather is if I keep them in the house. where it is warm.
Had two snowblowers running like charms a week before the first snow here. When I needed them, I started the tractor and got to the opposite end of the driveway before blowing the ground drive belt to bits (I ploughed a new garden with that tractor last fall with no problem). Anyway, no problem, went for the walk behind but, you guessed it, wouldn't start. Fortunately, my neighbour has a new snowblower that he is getting too old to follow around much. He even supplies the gas and comes out for a chat about the time I have his driveway finished but mine is still waiting.
