Carburetor Assembly (Wt-631)

Remove the air filter cover, air filter and filter support. Remove the fuel lines from the old carburetor, mark where they go, and remove the throttle cable. The remove the two screws that hold the air box and carburetor on. Remove old carburetor, be careful with the carburetor gasket because it does not include a new one. Install the new carburetor and air box with the two screws. Then hook up the fuel lines and throttle cable. Then the other parts in reverse order.

I started by removing the air filter cover, then the air filter, then the filter support. I then removed the fuel lines and throttle from the old carburetor. Making sure I noted where the fuel line had been. I then removed the two screws that hold the air box and carburetor on, along with the choke shutter and the choke plate. I then remove the old carburetor and installed the new one. Replaced the choke plate, choke shutter and air box and tightened the screws. I then installed the fuel lines and throttle on the new carburetor. Then the air filter assembly. I then replace the old spark plug with a new one and gapped it a 0.025 Primed it and choked it and it started right up.

I replaced the carburetor, replaced the fuel tank and replaced the air filter. Now my 16 year old trimmer starts up and runs like a new one. I am so glad that I found the parts on ereplacement parts.com.

Remove the housing to expose the carburetor. Simply removed the carburetor and replaced it. I would suggest replacing the fuel lines at the same time. Pretty easy job for $60 bucks vs well over at $100 at a repair shop.

Removed air cleaner and fuel lines. Removed carbeurator and replaced and reassembled.

Remove air filter assembly. Then remove the two screws that secure the carburetor. Pivot the carburetor to disengage the throttle linkage & remove the fuel lines. Remove the old carburetor, and install the new one. Reassemble in reverse order.
