Snow Blower Maintenance

Spread the love

Old man Winter is here. Snow blowers are a necessity in many parts of the country. Like any machine, they require to be maintained every once in a while.

The most important thing you can do to ensure that your snow blower is ready for that big snowfall coming your way is to maintain your fuel system. If it doesn’t want to start, it is typically a fuel problem.

The best time to prevent-system problems is in the spring time, prior to storage.

Make Sure the Carburetor Is Full of Gas

There are generally differences of opinion on this one. One school of thought says that closing off the fuel line and running the engine to empty the carburetor, will prevent varnish from clogging the jets that inhibit the engine from starting.

Snowblower Maintenance

Here is the problem though. Leaving the carburetor empty and exposed to air quickens oxidation and formation of varnish. The change of seasons means fluctuating temperatures and humidity, which also hastens the process through the year. Before you know it, tiny orifices in the carburetor get plugged up. Next Winter, you are in your garage smelling like gasoline while trying to spray carb cleaner on everything.

The easy solution to avoid all of this is to just add fuel stabilizer at the end of the snow season, run the engine for  just few minutes to allow the treated gas to get through your snow blower, then shut the engine off. Finally, you can shut off the snow blower’s fuel line for the summer. The treated fuel in the carburetor bowl will protect and keep your engine clean and ready.

I know some of you reading this will say you should run the carburetor empty, and that the gas will evaporate. True, but evaporation takes a long time, and at least your carburetor will be protected until then.

Stabilize the Gas In Your Tank

I can’t stress enough that you should treat your gas with fuel stabilizer before storage. Stabilized fuel will protect against oxidation and varnish through the summer.

Fight the Effects of Ethanol Gas

It is possible for melted snow to turn in to water and get into your gas tank, causing the bond between ethanol and gasoline to break down. This process is called phase separation. The ethanol and water mixture gets into the engine’s combustion chamber and caused your engine to run lean. Overtime this can damage your engine.

The best way to avoid phase separation is to use ethanol free gas. For many people, this is just not available though. What you can do instead is to use the best fuel additive, AMSOIL Quickshot, in your tank. AMSOIL Quickshot was developed to specifically address ethanol related problems.

If you use ethanol-blended gas, consider continuous use of a fuel additive, such as AMSOIL Quickshot, formulated to address ethanol-related performance issues. You can use AMSOIL Quickshot in any seasonal equipment like snow blowers, snowmobiles, motorcycles, ATV’s, cars, boats, lawnmowers, etc.

Change the Oil In the Spring

Its not secret that used oil is acidic and WILL corrode metal components if not changed on a regular basis. Before you put any of your machines into to storage or long periods of non use, change the oil to remove acidic byproducts and preserve maximum protection. After changing oil, be sure to run the engine for a few minutes so the oil can distribute to the lower end of the engine.

Use a Fogging Oil

AMSOIL Engine Fogging Oil provides protection against corrosion and will extend the life of your snow blower engine. You can also use fogging oil in your motorcycle, snowmobile, ATVs, lawn equipment, portable generators, hand-held power equipment, chainsaws, marine outboard motor, stern drive and inboard marine engines, personal watercraft, p motor scooters, powered farm equipment, powered construction equipment, cars and trucks. Your cylinders, piston, and valves will be protected during storage.

To use fogging oil, you just remove the spark plug, and spray a quick shot of fogging oil into the cylinder. Then, slowly pull the starter cord a few times, just to distribute the oil, then put the plug back in.

Check the gear housing

Make sure there is no debris around the filler port first, then remove the plug and make sure there is enough gear lube. It should be to the top. You can use our oil and filter lookup tool to find the correct gear for your needs.

  1. I do not own a snow blower but would love to in the future especially with our Ohio winters. I did not realize there was so much maintenance to keep it up and running, but I can recognize that it is necessary as with all motorized machines. Thank for all the info, myself as well as my stepdad will benefit greatly!

  2. This may be a silly question because I actually have an electric snowblower. It’s the Snow Joe if that matters.

    I understand that clearly I wouldn’t have to worry about the gas related pieces of the maintenance, but are there any additional items I should focus on for an electric snowblower? I know generally speaking electric engines require less upkeep than gas/oil based engines, but this is the first one I’ve ever bought!

  3. Hey Jim, I just placed my order yesterday and it is already on my front porch! I can’t believe how fast my AMSOIL order was delivered.  I knew that I was getting free shipping on AMSOIL products, but I didn’t know I was getting FAST SHIPPING ON AMSOIL products.

  4. I didn’t know that you had to do all of these things to protect a little machine like a snowblower. Well I guess maybe not so little. I don’t personally own a snowblower but my parents do. I wonder if they are aware of this? I will have to let them know everything you said about treating the gas with a stabilizer and things. I will be sure to forward a link to your post on to them. thanks!
