Pull the starter cord – that’s the first step to learn how to start a Briggs and Stratton snow blower. You need to check a few things first, like the fuel and the choke, to make sure it fires up right away.
We’ve all been there. A big snowstorm hits and you need to clear your driveway fast. You pull the cord and nothing happens. It’s a bad feeling when your machine won’t start.
I’ve used these engines for years. I know the little tricks that make starting easy every single time. It’s not as hard as it seems once you know the steps.
This guide will walk you through the whole process. We’ll cover everything from your first pull to fixing common problems. Let’s get your snow blower running.
What You Need to Know Before You Start
Before you learn how to start a Briggs and Stratton snow blower, you need to understand the parts. Knowing the names helps a lot. You won’t feel lost when I talk about the choke or the primer bulb.
The engine needs three things to run. It needs fuel, air, and a spark. If one of these is missing, your snow blower won’t start. Our job is to make sure all three are ready to go.
Check your owner’s manual first. It has the exact steps for your model. My guide is general, but your manual is specific. Keep it handy while you work.
Always work in a well-lit area. You need to see the controls clearly. Make sure you have enough space to pull the starter cord safely. You don’t want to hit anything.
Wear good boots with grip. The ground might be slippery from snow or fuel spills. Safety glasses are a smart idea too. They keep flying debris out of your eyes.
Let’s look at the key parts you’ll use. The fuel valve controls gas flow. The choke helps a cold engine start. The primer bulb adds extra fuel to the carburetor. You’ll use all of these.
The Step-by-Step Starting Process
Here is the full method for how to start a Briggs and Stratton snow blower. Follow these steps in order. Don’t skip any, even if you’re in a hurry.
First, move the snow blower to a clear, flat spot. Make sure the auger and drive controls are disengaged. The machine should not be trying to move or throw snow. This is a key safety step.
Next, locate the fuel valve. Turn it to the “On” position. This lets gas flow from the tank to the engine. If the valve is off, the engine gets no fuel. It will never start.
Now, find the choke lever. For a cold engine, move the choke to the “Full” or “Closed” position. This restricts air flow and makes the fuel mixture richer. A rich mixture is easier to start when the engine is cold.
Press the primer bulb three to five times. You should see fuel moving through the clear fuel lines. Don’t over-prime it. Too much fuel can flood the engine and make starting harder.
Grab the starter cord handle firmly. Brace yourself with one foot on the machine’s frame. Pull the cord smoothly and quickly. Do not yank it or let it snap back. The engine should cough and try to start.
If it starts but runs roughly, move the choke to the “Half” position. Let it run for 30 seconds to warm up. Then, you can move the choke all the way to “Off” or “Open”. Your snow blower is now ready to work.
Starting a Cold Engine vs. a Warm Engine
The steps change a bit based on the engine’s temperature. Knowing the difference is a big part of how to start a Briggs and Stratton snow blower correctly. A cold engine needs more help.
For a cold start, use the full choke. The engine metal is cold, so fuel doesn’t vaporize well. The choke helps by adding more fuel to the mix. This gives it a better chance to ignite on the first pull.
Press the primer bulb for a cold start. This shoots a small amount of raw fuel directly into the carburetor. It gives the engine a “boost” of easy-to-burn fuel for that initial start.
If the engine is already warm from recent use, you often don’t need the choke. Set the choke to the “Off” or “Open” position. You might not need to prime it either. A warm engine is much easier to start.
Sometimes a warm engine floods. This happens if you used too much choke or primer. If you suspect flooding, move the choke to “Off”. Then, pull the starter cord several times with the throttle wide open. This pulls in more air to clear out the extra fuel.
Listen to the sound. A cold engine will sputter and run unevenly at first. A warm engine should settle into a smooth idle right away. Adjust the choke based on what you hear.
Remember this simple rule. Cold engine = choke ON, prime it. Warm engine = choke OFF, maybe prime once. This rule solves most starting problems before they even happen.
Using the Primer Bulb Correctly
Many people get this step wrong. Using the primer bulb right is crucial to how to start a Briggs and Stratton snow blower. It’s not just about pushing it a bunch of times.
The primer bulb’s job is simple. It pushes fresh fuel from the tank into the carburetor bowl. This fills the bowl if it’s empty. It also adds a little extra fuel for starting.
Press the bulb slowly and firmly. Watch the fuel lines. You should see liquid gas flowing toward the engine. Each press should feel firm, then soft as it refills with fuel.
How many presses? For a cold start, three to five is the sweet spot. For a warm start, one or two is often enough. If the engine is hot from just being used, you might not need to prime at all.
A common mistake is over-priming. If you press the bulb ten times, you’re adding too much fuel. This can flood the engine. A flooded engine won’t start because the spark plug is wet.
If you think you flooded it, stop priming. Move the choke to “Off”. Hold the throttle trigger wide open. Then, pull the starter cord several times. This helps clear the excess fuel out of the engine.
According to the Briggs & Stratton website, proper priming is key for reliable starts. Their manuals always specify the right number of pushes. Check yours if you’re unsure.
Setting the Choke Properly
The choke controls the air-fuel mixture. Setting it wrong is a top reason people fail to start their snow blower. Let’s fix that for good.
When the choke is “On” or “Closed”, it blocks most of the air. This creates a very rich fuel mixture. A rich mixture is easier to ignite in a cold engine. It’s like giving the engine a strong cup of coffee to wake up.
Once the engine starts and runs for 20-30 seconds, it begins to warm up. You need to open the choke gradually. Move it to the “Half” position first. Let the engine run smoothly there for another 30 seconds.
Finally, move the choke all the way to “Off” or “Open”. The engine should now run on the normal air-fuel mix. If it sputters when you open the choke, move it back to half for a bit longer. The engine just needs more time to warm up.
What if your engine starts with the choke off? That’s great. It means the engine is warm enough or the weather is mild. Just leave it off. You don’t need to use the choke if the engine starts without it.
Remember, the choke is not a throttle. It doesn’t control engine speed. It only helps with starting. Once the engine is warm and running, the choke should always be fully open for normal operation.
The Consumer Reports guide to small engines says a stuck choke is a common issue. If your lever feels stiff, spray a little lubricant on the linkage. Make sure it moves freely before winter hits.
Pulling the Starter Cord the Right Way
This seems simple, but technique matters. A bad pull can hurt your arm or damage the machine. Let’s do it the safe, effective way.
Stand in a stable position. Place one foot on the frame of the snow blower for support. Hold the handlebar with your other hand for balance. You don’t want the machine moving when you pull.
Grip the starter cord handle firmly. Don’t wrap the cord around your hand. Use a firm, full-handed grip. Pull straight out, smoothly and quickly. You want a fast, sharp pull to spin the engine fast.
Let the cord return slowly. Guide it back with your hand. Never let it snap back on its own. A snapping cord can fray the rope and damage the rewind mechanism inside the starter.
If the engine doesn’t start on the first pull, don’t panic. Reset the cord fully. Then, pull again with the same smooth motion. Sometimes it takes two or three pulls, especially on the first start of the season.
For a cold engine, you might need to pull four or five times. That’s normal. If you’ve pulled ten times and nothing happens, stop. You likely have another issue like old fuel or a bad spark plug. We’ll troubleshoot that later.
Your pulling motion should come from your shoulder and core, not just your arm. A good, strong pull spins the engine faster. A faster spin gives a better spark and better compression. This makes starting much more likely.
What to Do If It Won’t Start
Sometimes, even with perfect steps, the engine refuses to start. Don’t get mad. Let’s walk through a simple checklist. This is the troubleshooting part of how to start a Briggs and Stratton snow blower.
First, check the obvious. Is there gas in the tank? It sounds silly, but we’ve all run out of fuel. The fuel valve must be in the “On” position. Make sure the spark plug wire is connected snugly.
Next, think about the fuel itself. Gas goes bad after about 30 days. Did you leave old fuel in the tank over the summer? Old fuel won’t burn well. It can clog the carburetor too.
Drain the old fuel if you suspect it’s bad. Use a siphon pump or tilt the machine carefully. Put in fresh, clean gasoline. Add a fuel stabilizer if you plan to store the machine again.
Check the spark plug. Remove the wire and unscrew the plug with a socket wrench. The electrode should be a light tan color. If it’s black and sooty or wet with fuel, it might be fouled. Clean it with a wire brush or replace it.
According to the Environmental Protection Agency, proper small engine maintenance reduces emissions and improves starts. A clean spark plug is a big part of that.
If you’ve checked fuel and spark, check air. Is the air filter dirty or clogged? A dirty filter chokes the engine of air. Remove the filter cover and take out the filter. Tap it gently to remove loose dirt. If it’s very dirty or oily, replace it.
Still no start? The carburetor jet might be clogged with old fuel gunk. This is a more advanced fix. You might need to clean the carburetor bowl and the main jet. Your owner’s manual has instructions for this.
