My snow blower was very difficult to start so I brought it to a small engine repair shop. The carburetor that came with the unit (a Toro) was plastic! I've seen a lot of carburetors in my life but never a plastic one, until now. Anyway he replaced the carburetor with a metal one ,spark plug and gas filter, and warned me several times about bad gas and the need to keep it for only 2-3 months, even when using Sta bil.

What do you do with your gas ( I have to mix it with oil) after it gets old?
Thanks
