You need to drain the tank and carburetor – this is how to get old gas out of a snowblower. The process is simple and can save you from costly repairs down the line.
Old gas turns into a sticky mess inside your machine. It clogs up the tiny parts that make your snowblower run. When spring comes, you might forget about your snowblower in the shed.
I’ve made this mistake myself. I left gas in my machine over the summer. Come winter, it wouldn’t start no matter how hard I pulled.
This guide will show you the right way to do it. I’ll walk you through each step, from start to finish. You’ll learn how to get old gas out of a snowblower the safe way.
Why Old Gas is a Big Problem
Gas doesn’t last forever. It starts to break down after about 30 days. This is true even if you use fuel stabilizer.
The broken-down gas turns into a gummy substance. This gum clogs the carburetor jets. These jets are tiny holes that let fuel into the engine.
When they get clogged, fuel can’t flow. Your engine won’t start or it will run poorly. You’ll pull the cord until your arm hurts with no luck.
According to the Environmental Protection Agency, proper fuel management is key for small engines. It helps cut down on air pollution from bad running gear.
Old gas can also damage rubber parts. Fuel lines and seals can dry out and crack. This leads to leaks and more repair bills.
Learning how to get old gas out of a snowblower stops these issues. It’s a basic skill every owner should know. It saves you time and money when the snow flies.
What You Need Before You Start
Gather your tools first. This makes the job go smooth and fast. You don’t want to stop halfway to find something.
You’ll need a siphon pump or a hand pump. A simple one from the auto store works great. You’ll also need a gas can to catch the old fuel.
Get some clean rags and a funnel. Safety glasses are a good idea too. Fuel can splash and you don’t want it in your eyes.
Have a small container ready for the carburetor bowl. A plastic tub or an old coffee can works fine. You’ll also need basic wrenches or sockets.
Check your owner’s manual for the right size. Usually it’s a 10mm or a small adjustable wrench. A flathead screwdriver helps too for the carburetor drain screw.
With these tools, you can tackle how to get old gas out of a snowblower. Being ready makes the whole thing less stressful. You’ll feel like a pro.
Step-by-Step: Draining the Fuel Tank
First, take your snowblower outside. Do this in a well-ventilated area. You don’t want fumes building up in your garage.
Make sure the engine is cool. Never work on a hot engine. Let it sit for an hour if you just tried to start it.
Place your gas can on the ground. It should be lower than the snowblower’s fuel tank. This helps the siphon work better.
Insert the siphon tube into the tank. Push it all the way to the bottom. You want to get every last drop of that old gas out.
Pump the siphon until fuel flows into your can. Keep going until the tank is empty. You might see the old gas is darker than fresh fuel.
This is the core of how to get old gas out of a snowblower tank. Once it’s empty, wipe around the fuel cap area with a rag. You don’t want dirt falling in when you open it next.
How to Drain the Carburetor Bowl
The carburetor holds gas too. You must drain this part as well. If you skip this, you didn’t really get all the old gas out.
Find the carburetor on your engine. It’s usually a small metal box with a fuel line going to it. Look for a small screw on the bottom.
This is the drain screw. Place your small container underneath it. Old gas will drip out here.
Use your screwdriver to loosen the drain screw. Turn it counter-clockwise slowly. Don’t take it all the way out, just loosen it enough for fuel to flow.
Let all the fuel drain into your container. It might be a few ounces. This fuel is often the worst because it’s been sitting in the bowl.
Tighten the drain screw back up when it stops dripping. Don’t over-tighten it. You could strip the threads or damage the carburetor body.
This step is crucial when learning how to get old gas out of a snowblower. The carburetor bowl is where problems often start.
Using Fuel Stabilizer for Storage
Now your system is empty. But what about next season? You need a plan to stop this from happening again.
Add fuel stabilizer to fresh gas. Do this before you put gas in the tank. Mix it well according to the bottle’s directions.
Fill your tank with this treated fuel. Run the engine for a few minutes. This gets the stabilized gas into the carburetor and fuel lines.
The US Forest Service notes that stabilized fuel can last up to two years. This is way better than untreated gas. It’s a simple trick that works.
I use this method every spring. I add stabilizer, run the engine, then store my snowblower. It starts right up next winter.
Some people say to store it with an empty tank. I like the stabilized fuel method better. It keeps seals moist and prevents rust inside the tank.
Either way works. The key is to have a plan. Don’t just park it with old gas inside. That’s asking for trouble.
What If the Gas is Really Old and Gummy?
Sometimes gas turns to varnish. It’s thick and sticky like syrup. Normal draining might not clear all of it.
You might need to clean the carburetor. This is a bit more involved. But it’s still a job you can do at home.
Remove the carburetor from the engine. Take off the fuel line first. Then unbolt the carburetor from the intake manifold.
Take it apart carefully. Note how the pieces go together. Soak the metal parts in carburetor cleaner overnight.
This cleaner dissolves the varnish. Use a small wire to clear the jets. Blow through the passages with compressed air.
Reassemble the carburetor and put it back on. This deep clean is part of how to get old gas out of a snowblower that’s been neglected for years. It brings old machines back to life.
Common Mistakes to Avoid
Don’t use your mouth to start a siphon. This is dangerous and tastes terrible. Use a pump siphon instead.
Avoid using dirty containers for the old gas. Dirt and debris can get into your fuel system. Always use clean fuel cans and funnels.
Don’t forget to drain the carburetor bowl. The tank is just one part of the system. The carburetor holds gas too.
Never work near an open flame or spark. Gas fumes are flammable. Turn off pilot lights and don’t smoke.
Don’t pour old gas down the drain or on the ground. This is bad for the environment. Take it to a hazardous waste disposal site.
Many towns have collection days. Your local garage might take it too. Check the EPA’s hazardous waste page for guidance.
Avoid these mistakes and you’ll master how to get old gas out of a snowblower. You’ll keep your machine running for many winters.
Tips for Easier Winter Starts
Use ethanol-free gas if you can find it. Ethanol absorbs water from the air. This water causes corrosion and phase separation.
Phase separation is when ethanol and water sink to the bottom. This layer can’t burn in your engine. It causes running problems.
Store your snowblower in a dry place. Damp sheds promote condensation inside the fuel tank. A dry garage is better.
Run your snowblower dry at the end of the season. Or use stabilized fuel as I mentioned. Both methods work well.
Check the spark plug each fall. A fresh plug helps with cold starting. It’s a cheap part that makes a big difference.
Follow these tips and you’ll rarely need to know how to get old gas out of a snowblower. Prevention is easier than the cure.
When to Call a Professional
Sometimes the damage is too much. If you’ve tried everything and it still won’t start, get help.
A small engine repair shop can fix it. They have special tools and knowledge. It might cost less than you think.
If you see fuel leaking from the tank or lines, get it fixed. Leaks are a fire hazard. Don’t ignore them.
If the carburetor is damaged from corrosion, you might need a new one. Some are cheap and easy to replace. Others are more complex.
The Consumer Reports website has good advice on small engine repair shops. Look for certified technicians with good reviews.
Knowing how to get old gas out of a snowblower is great. But also know your limits. There’s no shame in asking for help.
