Snow blower has had gas in it two years and not started. What do I do?
Put Sea Foam in it and start it.
It may take running it a few times to get it corrected.
Have you tried starting it? If you did, and it didn't work, you may have to clean out the carb/fuel system.
If you haven't tried starting it, I'd suggest trying to drain all the old fuel out, and put fresh in, then try starting it.
I have an old motorhome that sits more than it goes, the generator runs off the same fuel in the main tank. The generator runs maybe once a year for 10-15 minutes. I've not had a problem starting it even though it's been on E-10 for five years now.
I know I need to run it more often, but I really just forget to go do it. Out of sight, out of mind.
Pull off the spark plug.
Blow out the cylinder with “something”.
Last time I forgot to drain my mower, I put a shot of Hoppes #9 gun cleaner inside it and put the plug back on. Started up with a vengeance.
Blow out the cylinder and plug with carburetor cleaner. Leave a little in the cylinder and start it up.
Drain all the old gas. Replace with fresh gas. Try and start it. If it will not start then:
Shut off the fuel petcock. Record how many turns the low and hi speed needles are from being seated. Tear down and clean the carburetor. Adjust the lo and hi speed needles to their original positions. Put it all back together. Turn on the fuel petcock.
Give it a try.
I wouldn’t try starting it. Try to drain as much gas as you can, even the carburetor float bowl if possible. The less old gas you have in it, the less varnish will develop.
Easy for me to say, but I will anyway: I always add stabilizer to the fuel for all of my small engines, and for the ones that I don’t use much, I do drain them after use. Part of the draining is to leave a tiny bit of fuel in the tank, start the engine, and let it run until it dies (runs out of gas). If you have more than a tiny bit of fuel in the tank, you’ll quickly learn just how efficient gasoline is, as the engine will seem to run forever.
Buy a new carburetor.
