How to Replace a Carburetor on a Riding Lawn Mower

This video shows how to replace the carburetor in your riding lawn mower or lawn tractor. The carburetor blends air and fuel to produce a combustible mixture for the engine cylinder. If the carburetor has water damage or is clogged with dirt, debris or gummed-up gasoline, the engine might surge or be hard to start. Replace a damaged or clogged carburetor with a part that fits your model. If the carburetor isn't beyond repair, you can rebuild it instead of replacing it. Check out this video to see how to rebuild the carburetor.

The first step to replacing the carburetor is to turn the ignition switch off and remove the key. Lift the seat. Remove the bolt connecting the negative cable to the battery and tuck the battery cable away so it doesn't touch the battery post. Lift the mower hood. We’ve removed the hood to give you a better view. Remove the air duct mounting screws and pull off the air duct. Rotate each air filter cover retaining knob counterclockwise and pull off the air filter cover. Remove the air filter. Remove the air filter housing screw. Remove the front blower housing mounting bolts. Remove the rear blower housing mounting bolts. Lift off the blower housing. Remove the lower dash fastener and pull off the lower dash. Clamp off the fuel line with hose pinch-off pliers. Release the clamp that attaches the fuel line to the carburetor and pull the fuel line off the carburetor. Use a shop rag to catch drips. Remove the air intake mounting nuts. Detach the breather tube and remove the air intake. Disconnect the wire from the fuel solenoid. Take a digital photograph of the carburetor linkage connections to document their location for reassembly. Remove the carburetor mounting studs. Disconnect the throttle rod and the throttle spring. Disconnect the choke rod. Pull off the carburetor. Remove the intake gasket on the engine and clean the gasket mounting surface. Position the new carburetor near the engine and reconnect the choke rod. Connect the throttle rod and spring. Install the new intake gasket on the engine. Attach the carburetor on the engine with the mounting studs. Tighten the studs firmly. Connect the fuel solenoid wire. Attach the breather tube to the air intake and connect the air intake to the carburetor. Install the air intake mounting nuts. Attach the fuel line to the carburetor. Remove the hose pinch-off pliers from the fuel line. Reinstall the lower dash and secure it with the fastener. Position the blower housing on the engine and align the air diverter in the housing. Reinstall the blower housing mounting bolts. Reinstall the air filter housing screw. Reinstall the air filter. Position the air filter cover on the engine and turn each retaining knob clockwise on the cover. Reinstall the air duct and secure it with the mounting screws. Reconnect the negative cable to the negative battery terminal. Lower the seat.

Where can i find the air intake peace that goes to the fron of the carburetor? Mine got melted and trying to replaice.

[Ruraloutlaw]

whats the little steel elbow that goes from the carb to the fuel line? Mine broke and I am having issues finding one to replace

[TheFirstBigBoy]

Idle too high. How does this model, adjustment screw?

[aliciaenterline]

Have a craftsman riding lawnmower. It stalls when i let off clutch. I changed gas filter but that didn't work. Anyone have any ideas what's wrong?

[jacobdaniel]

I forgot to take a picture of the throttle spring, can y'all send me one? I don't know how to hook it up and my engine is running very rough without it

[ezequielmaldonado]

Do u have a part number for that carburator

[davidcrawford]

I replaced my carburetor hoping it would fix my throttle problem. My throttle still cause the engine to cut out instead of speeding up. So I can't move my throttle past the mid position.

Don’t even bother trying to rebuild one of these carbs. The kit costs half as much as the carb and you don’t get much with it that is any use to you. For another $50 you can get the entire carb. Expensive lesson learned.

[kcscott]

You need o do one on the v-twin carbs like #796227

So nothing on how to test the linkage is working as planned before reattaching. Reassemblke whole machine in toto before checking the linkage works. Which was why I wasted 3 minutes watching this. Not the only one from comments below. If you are attaching / detaching linked ite, s you should always check they work as planned before encasing in the rest of the stuff

[matthewgarrett]

Anyone forgetting that this doesn't solve anything until you adjust it. Can't get it adjusted

[bertiemcgarvey]

Why all the nonsense about disconnecting the battery which has nothing to do with tuning the carburettor?
