1. Removing the Carburetor from the Cub Cadet Snowblower
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 Cub Cadet 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.
We are going to the next phase of disassembling our Cub Cadet Snowblower’s carburetor.
2. Disassembling Cub Cadet 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
To clean its exterior, spray some carb cleaner all over your Cub Cadet carburetor. 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 Cub Cadet Snow blower Carburetor
It’s time to clean the Cub Cadet carburetor thoroughly inside 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 Cub Cadet 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 both 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 Cub Cadet Snowblower Air Filter
Always remember to check that the snowblower air filter is clean before starting up its engine. This will allow clean air to enter the carburetor because dirty air from the snow thrower air filter will reverse the progress you just made.
