One of the ways to return a 4-cycle engine to peak performance is to clean the small engine carburetor. In some cases all that is needed is an adjustment, where carburetor cleaner is used to clean the exterior and the small passages, and a carburetor kit is used to replace old and worn out carburetor parts.
In more extreme cases when old fuel has blocked the ports and passageways of the carburetor, a complete replacement may be necessary.

Below are the materials that you will need along with the step-by-step procedure on how to adjust a snowblower carburetor.
The air filter is a device with pleated screens rectangular in shape sitting on top of the carburetor. The air filter is your first line of defense against air contaminants such as road salt, tiny dirt pieces, dust and pollen.
Remove the screws on the clamps that hold the air filter to the carburetor using a screwdriver to remove the air filter. Set the air filter aside. Removing the air filter will reveal if your carburetor needs a simple adjustment or replacement.
Corrosion is one of the major signs that you need to replace your carburetor so check for rust spots and other signs of corrosion. The idle screw is responsible for controlling how much air enters the carburetor once you apply the throttle of the snowblower. Reducing the amount of air that enters the carburetor is simply done by turning the idle screw clockwise.
On the other hand, increasing the amount of air that enters the carburetor is done by turning the idle screw counter-clockwise.
Make the necessary adjustments to the idle screw. Turning the idle screw clockwise lessens the power of the snowblower engine and decreases its fuel consumption. Turning the idle screw counter-clockwise increases the power of the snowblower engine as well as its fuel consumption.
Make the desired adjustments for the power and fuel consumption of your snowblower engine.
Adjust the low-speed needle using the adjustable wrench. The low-speed needle can be found within the fuel intake area of the carburetor. Make the necessary adjustment to set the desired engine idle-speed of your snowblower. Using a Phillips screwdriver, adjust the choke of the carburetor. The chalk valve screw is a Phillips screw with a small spring on it. Increase the power of your snowblower engine by loosening the screw of the choke valve.Modify Snowblower to never clog and throw twice as far w/ Impeller Kit
This will allow the choke valve to open wider and increase the amount of fuel intake. Tightening the screw of the choke valve decreases the power of your snowblower engine. The last step in adjusting your snowblower carburetor is to re-attach the air filter that you removed in step 1.
Before re-attaching the air filter make sure to clean it using a soft brush to remove the dirt and dust on its pleated screens.Storing a snow blower in is much different than it was in Today, ethanol-blended fuels and efficiency standards for outdoor power equipment require snow blower owners to be extra attentive to their machines at the end of the season. If these critical steps aren't completed correctly or skipped, it's quite possible your snow blower won't even start next season, leaving you with a shovel, frustration and a repair bill.
That's a common Google search entry and it's a common issue with outdoor power equipment today. A snow blower that won't start is the biggest source of frustration when the big storm hits, and usually, it's because of nothing more than a clogged fuel line. Due to today's efficiency mandates from the U. Government, small engines are required to use less fuel.
If fuel can't pass through the tiny hole in a carburetor pilot jet see photothe fuel flow is stopped and the engine won't run. All it takes is the smallest obstruction to ruin a Saturday night snowfall. Gasoline today is a lot different than it was in In fact, it's not even gasoline, it's a blend of fuel. Today, most regular, unleaded gasoline is an E10 blend, meaning it contains up to ten percent ethanol.
Though E10 blended fuels are technically acceptable for use in a snow blower, use of percent gasoline in a small engine is best.
Even the lowest ethanol content can damage a small engine. Ethanol fuels can lead to engine damage and increase the possibility a snow blower engine won't start. Ethanol is problematic in small engines for numerous reasons and storing a small engine with ethanol-blended fuel in the tanks is especially risky.
Because ethanol dissolves old gum and varnish deposits in the fuel system and tank. Once dissolved, those small particles can enter the engine's fuel lines and clog the tiny hole in the carburetor jet. To help reduce the possibility of ethanol-related problems in a snow blower engine, add Ariens ethanol fuel treatment to the fuel tank.
To avoid ethanol-related problems in your snow blower engine, we suggest using percent gasoline, especially leading up to storage. Type the heading of this paragraph into a Google search to find pumps with percent gasoline.
Using fuel stabilizer in your snow blower engine will help prevent gasoline from deteriorating, turning to a gel and clogging the fuel system.
All fuels, both ethanol-based blends and percent gasoline, oxidize and break down. Gasoline and gasoline blends can deteriorate in as little as two weeks and leave a gel and a varnish in the fuel system, and clog it. To help prevent gasoline from breaking down in the fuel tank, Ariens recommends adding a quality fuel stabilizer to fresh gasoline.
Treating fresh gasoline less than two weeks old preserves the fuel during storage and prevents it from breaking down and clogging the fuel system. Just be aware, fuel stabilizer only keeps fresh fuel fresh; old fuel cannot be rejuvenated with fuel stabilizer.
Snow blower gasoline older than two weeks should not be stabilized before summer storage. Instead, it's recommended to completely drain that fuel tank, then run the engine until all fuel that was in the fuel lines and carburetor is used and the engine stops on its own. Detailed instructions can be found in the snow blower operator's manual. Because of all the moisture and ice-melting agents like salt that contact a snow blower, corrosion and rust can build up between the wheel hubs and the axles.
If the axles aren't periodically cleaned and lubricated, they could rust together. If a wheel is permanently fused to its axle, accessing the hardware to remove the bottom cover on the unit will be a very inefficient and unpleasant experience. Remove each wheel from the axle. If rust is present on the axles, remove it with sandpaper, wipe clean and coat with a thin to medium layer of grease.
