A carburetor kit has everything you need to tear down and rebuild the carburetor in your snow blower. It is a great way to extend the life of your carburetor, as it essentially restores your carburetor to new condition, which will help keep your engine running smoothly. When rebuilding the carburetor, it’s a good idea to take pictures of all the parts as you take it apart so you know where they go when you reassemble it at the end. We also recommend you lay all of the parts out in the order you took them off, which will make reassembly much easier as well. All snow blowers are a little different, depending on manufacturer and model, so the process will vary slightly. With some models, the carburetor is already exposed, if yours is, skip the instructions that are not relevant to you.
If necessary, start by removing any covers or...
A carburetor kit has everything you need to tear down and rebuild the carburetor in your snow blower. It is a great way to extend the life of your carburetor, as it essentially restores your carburetor to new condition, which will help keep your engine running smoothly. When rebuilding the carburetor, it’s a good idea to take pictures of all the parts as you take it apart so you know where they go when you reassemble it at the end. We also recommend you lay all of the parts out in the order you took them off, which will make reassembly much easier as well. All snow blowers are a little different, depending on manufacturer and model, so the process will vary slightly. With some models, the carburetor is already exposed, if yours is, skip the instructions that are not relevant to you.
If necessary, start by removing any covers or shrouds around the carburetor. You may need to remove the handle bar on some models to pull off the covers. Remove any knobs, disconnect any switches and fuel lines on the primer bulb. You will then need to remove the cover that houses the knobs, switches and primer bulb. Remove the choke lever carefully. Make sure you pinch off the fuel line to prevent fuel from leaking out of your snow blower. Remove the fuel line and slide the choke control plate off the carburetor, and disconnect the linkage from the control plate and carburetor. Disconnect the throttle rod return spring, and remove the throttle rod from the carburetor.
You should now be able to slide the carburetor right off. Take it over to a workbench and start disassembling it. First remove the nut on the bowl, and then remove the bowl and gasket. Next, remove the float pin and float valve. Unscrew the main jet screw and dump it out with the emulsion tube. Remove the plastic throttle stop, and the metering plug out of the carburetor. You should now spray the carburetor, fuel bowl, and all the small orifices with carburetor cleaner then carefully wipe it all clean. Inspect the carburetor and all the components for any signs of damage. If there is any corrosion inside the carburetor it will need to be replaced.
Now you need to put everything back together. Start that process by installing a new emulsion tube, and new main jet. Make sure those parts are secure, then firmly press the new metering plug into place. Reinstall the throttle stop screw; this should be screwed in until approximately 1/16 of an inch sticks out the other side. Place a new spring on the needle valve, and snap the new needle valve into the new float. Reattach the float to the carburetor with the new pin. Install a new O-ring on the bowl before reinstalling. After you have completed the rebuild you can then reinstall the carburetor and the gasket onto the engine. Reattach the throttle cable and fuel line, and unpinch the fuel line. Reinstall the cover that houses all the knobs, switches, and primer bulb, making sure you hook everything back up. Reinstall all the covers and shrouds and the handle bar.
