1. Removing the Carburetor from the Briggs and Stratton Snow blower

Follow these steps carefully to revive your carb and of course snow blower:

Remove the Cover

Unscrew all 6 bolts with a socket wrench and set the cover aside attached to the exhaust guard.

Remove the Fuel line

First, Turn off the fuel supply or clamp the Briggs and Stratton snow thrower’s fuel line with the fuel line clamp.

Now slide the clip on the fuel line up and pull the line away from the carb.

Pull Off the Primer line

Pull the primer line away from the carburetor after removing its clip.

Removing the Throttle Cable

To fully remove the carburetor, you must first remove its throttle cable.  Slide the carb a little bit away from the body. Now slide the throttle inside and pop up the throttle cable to release it.

Now we are going to the next phase of disassembling our Briggs and Stratton Snowblower’s carburetor.

2. Disassembling Briggs and Stratton Snow Thrower Carburetor

Remove the Gaskets

Peel off the gaskets from both ends of the carburetor using your fingers.

Empty the Carburetor Bowl

If you don’t want any fuel in your workspace then empty the carburetor completely, before tearing it apart. Pull off the bolt(mentioned in the picture below) to drain the fuel from the carburetor bowl or its base. Collect the fuel in any empty container.

Clean the exterior of the carburetor

Spray some carb cleaner all over your Briggs and Stratton carburetor to clean its exterior. This way any dirt or grime on the outside will never get inside once the carburetor is opened.

Remove the Carb Bowl

Open the Carburetor bowl by removing the other bolt in the bowl. Remove any remaining fuel in it.

Release the Float

Slide the hinge pin with your fingers or pliers to remove the float. Set the pin and the float aside.

Note: Never spray carburetor cleaner on the float with the float needle on it. The float needle has a rubber seal that can be damaged by the chemicals in the carb cleaner.

Remove Main Jet

Take a flathead screwdriver and remove the main jet from the center or ‘neck’.

Remember that always use good quality flat-head screwdriver to unscrew the main jet. This is because main jet is made from soft metal and you can easily damage it with a slight wrong move.

Remove the emulsion tube

After removing the main jet, push the emulsion tube out of the ‘neck’ by inserting a flat-head screwdriver into the carb venturi.

Remove the O-ring

Finally, remove the O ring that seals the fuel bowl.

Note: Never spray carburetor cleaner on the o-rings. The o-rings are rubber seals that can be damaged by the chemicals in the carb cleaner.

3. Cleaning the Briggs and Stratton Snow blower Carburetor 

It’s time to clean the Briggs and Stratton carburetor thoroughly inside and out to remove any accumulated dirt or fuel residuals.

Spray each passage/opening of the carburetor

Spray in each and every big or small opening of the carburetor with a good quality carb cleaner to get rid of dirt, grime, and other residuals.

Always place a container below before spraying the carb cleaner.

Spray The Main Jet

The most important part of the Briggs and Stratton snowblower’s carburetor is its main jet. There is a tiny hole in it that is responsible to let the fuel go into the engine. If this got blocked the engine will run lean and creates problem in starting.

Most of the time it got clogged up or blocked, so we have to do this exercise. Spray it again and again until the hole is cleared of dirt or any blockage.

Other components of the Carb 

Spray the emulsion tube, and bowl. These are the other important parts of a carburetor that must be cleaned thoroughly before they can be reassembled. Spray carb cleaner at each of these parts well enough so that the carburetor can be used for a long time again.

Use a soft brush or a toothbrush 

Rub all the parts with a toothbrush or other small soft brush to further clean the carb.

Note: Don’t use a wired brush or any hard brush on the internal parts of the carburetor. It can damage them and affect the efficiency of the engine.

If you want, re-spray each part again after brushing.

Dry With A Clean Cloth

Now dry each component with a soft and clean cloth.

Reassembling the Carburetor

Set the emulsion tube

Put the emulsion tube back into its place by just sliding it with the screwdriver.

Place the Main jet

Reinstall the main jet after the emulsion tube and tighten it with the same screwdriver.

Reinstall the Float

Secure the float by inserting the hinge pin.

Put the O-ring

Reinstall the o-ring by simply pushing it with your hand on the edge of the fuel bowl.

Reassemble the fuel bowl 

Place the fuel bowl onto the carb body and tighten it with the wrench.

Put the Gaskets back on 

Now reattach bother gaskets on both sides of the carburetor.

Attach with the Engine

Slide the carburetor back onto the mounting bolts.

Attach Throttle Cable

To attach the throttle cable, push the throttle towards you and slide the cable into it. Now release the throttle.

Reinstall the Fuel line and Primer Line

Finally, attach the primer line and the fuel line to their place. Now you can switch on the fuel supply.

Attach the cover

Attach the cover and tighten all 6 screws to complete the cleaning.

Check Briggs and Stratton Snowblower Air Filter
