Thanks for the help, but with the mixed anwers, I think I will play it safe and start my fires with it..
Nope, You're good to go burning it in the snow blower.
You can run snowblowers and chainsaws on bacon grease - I'd run it. I sure wouldn't use gas that has 2 stroke oil in it as starters for your marshmello roasting fire.
oldjeep is absolutely correct. Small carburetored, unsophisticated engines will run on just about anything. I have ran my garden tractor with coleman lantern fuel, kerosene, wood alcohol,and lots of old boat fuel.
