On the engine’s side or top – that’s where the air intake on a snowblower is located. It’s a small, covered hole that pulls in clean air for the motor to run.
You need to find it for basic upkeep. A clogged intake makes your machine run poorly or not start at all. I’ve seen this happen many times in the middle of a storm.
It can be tricky to spot if you don’t know what to look for. The cover might be plastic or metal. It often looks like a small box or a round cap.
Let me show you exactly where to look on your model. I’ll also explain why it matters so much for your machine’s health.
What Is the Air Intake and Why It Matters
Think of the air intake as your snowblower’s nose. It breathes in air to mix with fuel inside the engine. This mix is what makes the motor run and create power.
If the nose gets stuffed up, the engine can’t breathe. It will sputter and stall. You might think you have bad gas or a weak spark plug.
The real problem is often a dirty air filter. That filter sits right inside the air intake housing. Its job is to stop dust and snow from getting into the engine.
Finding where the air intake on a snowblower is located is step one. Step two is checking that filter. A clean filter means your machine gets all the air it needs.
According to the EPA, small engines need proper air flow to burn fuel cleanly. A blocked intake makes the engine work too hard. It can also cause more smoke and waste gas.
So knowing this spot isn’t just about fixing a problem. It’s about stopping problems before they start. A quick check takes two minutes and saves you a big headache.
Common Air Intake Locations on Snowblowers
Most air intakes are in one of three spots. The exact place depends on your snowblower’s brand and how old it is. Let’s walk through the most common ones.
First, check the side of the engine. Look for a small, square plastic or metal box. It’s often held on by one or two screws or a metal clip.
This side location is very common on older two-stage models. The cover might say “Air Filter” on it. If you see those words, you’ve found the right spot.
Second, look on the top of the engine. Many newer models put the intake up top. This keeps it away from blowing snow on the ground.
A top-mounted air intake on a snowblower usually has a round or oval cover. It might look like a small dome or a flat panel. You often need to remove the fuel tank cap to get to it.
Third, some intakes are on the back of the engine. This is less common but happens on certain brands. Always look for a covered opening that seems intentional.
If you’re still stuck, grab your owner’s manual. The diagram will show you exactly where the air intake on a snowblower is on your model. No manual? A quick online search with your model number works too.
How to Locate the Air Intake on Your Specific Model
Let’s get practical. Here’s my step-by-step method for finding this part on any machine. I use this every time I help a friend with their snowblower.
First, make sure the engine is off and cool. Safety first. You don’t want to touch a hot engine or have it accidentally start.
Next, follow the carburetor. The carburetor is a small metal part on the side of the engine. Fuel lines and a throttle cable connect to it.
The air intake on a snowblower connects directly to this carburetor. Look for a hose or a metal tube coming out of the carb. Follow that tube. It will lead you right to the air filter box.
That box is your air intake housing. The Occupational Safety and Health Administration says to always disconnect the spark plug wire before service. Do this to be extra safe.
If your model has a plastic shroud over the engine, you might need to remove it. This is common on newer machines. Look for a few plastic clips or screws holding it on.
Once the shroud is off, the engine parts are exposed. The air intake will be much easier to spot. Remember to put the shroud back on when you’re done.
Identifying the Air Intake Cover and Housing
You’ve found a likely spot. Now, how do you know it’s the air intake and not something else? Look for these tell-tale signs.
The cover will be removable. It’s not a permanent part of the engine. It’s designed to come off so you can check the filter inside.
It might have a wing nut, a simple screw, or a metal spring clip holding it on. These are fasteners you can remove by hand or with a basic screwdriver.
The housing itself is usually a black or beige plastic box. On some older machines, it’s made of metal. It will have an opening that faces away from the engine’s center.
That opening is where fresh air gets sucked in. You can sometimes feel a slight vacuum if you put your hand near it while the engine runs. Don’t do this with loose clothing or gloves, of course.
If you see a small, round paper or foam filter inside, you’ve hit the jackpot. That’s the air filter. The housing that holds it is the air intake on a snowblower.
Still unsure? Take a picture and ask at a local small engine repair shop. They can confirm it in seconds. It’s better to ask than to poke around the wrong part.
Why You Need to Find the Air Intake Regularly
This isn’t a one-time search. You should check this spot a few times each season. Snow and ice love to clog things up.
A blocked air intake makes your engine run “rich.” This means too much fuel and not enough air. You’ll notice black smoke from the exhaust and a loss of power.
In bad cases, the engine won’t start at all. You’ll pull the cord over and over with no luck. I’ve been there, and it’s no fun in freezing weather.
Knowing where the air intake on a snowblower is lets you do a quick visual check. Before you start the machine, just glance at it. Make sure the cover is on tight and the area is clear of snow.
The Consumer Reports guide to outdoor power equipment stresses regular air filter checks. It’s one of the top three upkeep tasks for any small engine.
It also helps you diagnose problems. If your snowblower acts up, the intake is a great first place to look. It’s an easy fix that solves a lot of common issues.
Step-by-Step Guide to Checking Your Air Intake
Okay, you found it. Now what? Let’s walk through what to do next. This is basic upkeep anyone can handle.
First, remove the cover. Use a screwdriver if needed, but be gentle. The plastic can crack in cold weather if you force it.
Take out the air filter. It might be a flat paper filter, a round foam sleeve, or a combination of both. Note how it sits so you can put it back the same way.
Tap the filter gently on a hard surface to knock out loose dirt. Don’t blow into it with your mouth, as moisture from your breath is bad for it.
Hold the filter up to a light. Can you see light through it? If not, it’s too dirty and needs to be replaced. A dirty filter is as bad as no filter at all.
While the filter is out, look inside the air intake housing. Use a flashlight to check for leaves, mouse nests, or packed snow. Clean out any debris you find.
Reinstall the clean or new filter. Put the cover back on and tighten the fastener. Don’t over-tighten it. You just need it snug so no unfiltered air can sneak in.
Common Mistakes When Looking for the Air Intake
People get this wrong all the time. I’ve made some of these mistakes myself. Let’s learn from them so you don’t have to.
The biggest error is confusing the exhaust for the intake. The exhaust is where hot gas comes out. It’s usually on the opposite side of the engine and has a muffler attached.
The air intake on a snowblower pulls air in. The exhaust pushes it out. They are two different systems. The intake cover is cooler and connects to the carburetor.
Another mistake is not looking behind accessories. Sometimes the intake is hidden behind the primer bulb or the choke lever. Move these parts gently to see behind them.
People also forget to check under the fuel tank. On some models, the whole tank sits over the air box. You might need to loosen the tank to see the intake below it.
Don’t force anything. If a cover won’t budge, it might not be the right part. The air filter cover is meant to be removed easily for service. If it’s stuck on with more than clips or a screw, double-check your manual.
Finally, don’t ignore it once you find it. Mark the spot with a piece of tape or take a photo. This way, you’ll remember where the air intake on a snowblower is located next season.
Tips for Keeping Your Air Intake Clear in Winter
Winter is tough on machines. Snow is wet and packs easily. Here are my best tips for keeping that airway open all season.
After each use, brush off loose snow from around the engine. Pay special attention to the area where you know the air intake is. A small brush works great for this.
Never store your snowblower with a wet cover of snow on it. Let it melt and dry in a garage or shed before you put it away. Moisture leads to rust and ice in small openings.
Consider a simple block-off plate. Some people use a piece of cardboard or plastic to cover the intake opening during storage. This keeps mice and dirt out. Just remember to remove it before you start the engine.
Check the intake area if you’re expecting a very heavy, wet snow. This type of snow is more likely to get sucked in and cause a clog. A quick pre-storm glance takes two seconds.
The National Weather Service provides forecasts that can help you plan. If a big storm is coming, do your upkeep the day before. A clean air intake on a snowblower means one less thing to worry about.
Keep a spare air filter on hand. They are cheap and easy to swap. If you check yours and it’s filthy, you can change it right away and keep working.
What to Do If Your Air Intake Is Damaged
Sometimes the housing or cover gets cracked. This is a problem. Unfiltered air can now enter the engine, bringing dirt with it.
Dirt inside an engine acts like sandpaper. It wears down the cylinder walls and piston rings. This leads to expensive repairs or a dead engine.
If the plastic housing is cracked, you need to replace it. Don’t try to tape it up. Tape won’t seal properly and can come loose, making the problem worse.
Find your engine’s model number. It’s stamped on a metal tag on the engine itself. Use that number to order the exact replacement part online or from a dealer.
While you wait for the part, don’t use the snowblower. Running it with a broken air intake on a snowblower is a sure way to cause bigger damage. It’s not worth the risk.
Install the new part carefully. Make sure all the h
