I have an Ariens Deluxe 28 snow thrower that’s about 3 years old. I always run the carburetor dry after use. Upon first use this year, had a lot of trouble starting, and now it runs rough, and only stays running with choke applied. I’m assuming I have carb deposits. Can I solve the problem by using Sea Foam mixed into the gasoline? If so, what mix ratio should I use, and how long should I expect to run the engine to resolve the issue?
We love these questions Dan! First thing is to get your snow blower running again. If the tank and carburetor are empty, eyeball approx 2 ounces of Sea Foam into the tank followed by 8 or so ounces of fresh gasoline. Crank or rope pull the engine several times to draw the Sea Foam and gas mixture through the carburetor circuits, then let it sit overnight to soak. The mixture will work to dissolve any restrictive varnish from the fuel passageways, plus will add lubricity to the carburetor. Once you get the engine running again, add fresh fuel and wait for things to smooth out and return to operating power. [Should straighten out within 5 minutes of idling.]
If the treatment works we’ll suppose that you’re a convert. To avoid future trouble, add Sea Foam to every tank to keep the carburetor clean and lubricated. Sea Foam also works to stabilize fuel while the snow blower sits between snowstorms. No need to drain the carburetor, but that’s up to you.
