Carburetor Replacement On A Generator

by Jeremy HIPA 14 Dec 2022 0 Comments

This blog is a step-by-step instruction for replacing the carburetor on a generator. The most common reasons for replacing the carburetor is when it is clogged, causing the engine to not run, run poorly, or only run for a few seconds, and cleaning the carburetor does not solve the problem.


Before you begin the replacement, you need to make sure the engine has cooled, remove the wire and boot from the spark plug to prevent the engine from accidentally starting and close the fuel valve.
Step 1: Use a 5/16 inch socket to remove the mounting screws securing the air filter cover and pull the cover and filter off. Place the choke lever in the choke position then pull the lever up to remove. Detach the breather tube from the filter housing.
Step 2: Next use a ten millimeter socket to remove the mounting nuts securing the housing. Pull the housing off of the mounting posts and move it out of the way.
Step 3: Release the clamp securing the fuel line to the carburetor and pull the fuel line off. Be prepared for some fuel to spill.
Step 4: Remove the air filter housing gasket then use an e5 external torque split to unthread the mounting posts securing the carburetor. Detach the throttle linkage and spring to completely remove the old carburetor. And now you are ready to install the new carburetor.
Step 5: First remove the choke plate and shaft, transfer the seal from the removed choke shaft to the choke shaft appropriate to your engine model. Position the new shaft then insert the choke plate and snap it into place.
Step 6: Next install the new throttle linkage and spring on the throttle arm. Connect the throttle linkage and spring to the new carburetor. Insert the mounting post into the new carburetor and slide on the new spacer gasket along with the existing spacer. Then thread the mounting posts into the intake manifold and tighten with the e5 external spit.
Step 7: Attach the fuel line to the carburetor and secure it with the retaining clamp. Slide the air filter housing gasket onto the mounting posts. Realign the air filter housing and replace the mounting nuts to secure.
Step 8: Reattach the breather tube to the filter housing and make sure the new choke shaft is in the choke position then push the new choke lever into place. Reposition the air filter and cover, rethread the mounting screws to secure. Open the fuel valve, reattach the wire and boot to the spark plug and the engine should be ready for use.
