How to Adjust a Riding Mower Carburetor

Riding mowers feature gasoline engines as a power source for propelling the mower and turning the cutting blades for grass cutting. A carburetor on the engine controls the gas flow from the fuel tank to the engine. With normal use, the carburetor may get out of adjustment, resulting in less than optimal performance of the engine and mower. The carburetor can be adjusted to control the idle speed, high speed and choke.

Adjust Idle Speed Mixture

  1. Locate the air filter and air filter cartridge on the top of the riding mower engine. With the engine off and cooled down, loosen the nut on the air filter cover to remove the filter and cartridge. Gumout recommends spraying carburetor cleaner onto the carburetor to remove any debris and gunk that may have accumulated.

  2. Locate the idle adjustment screw on the carburetor. Turn the screw clockwise with a screwdriver until the needle on the end of the screw just barely touches the seat. Then turn the screw 1 1/2 turns counterclockwise.

  3. Locate the main jet adjustment screw at the base of the float bowl; the carburetor you are working on may or may not have this, depending on the manufacturer and model. Turn the screw clockwise until the needle on the end of the screw just touches the base then turn the screw counterclockwise 1 1/2 turns.

  4. Place the air filter cartridge and filter, but leave the cover off for now. Start the engine and allow it to run for about 5 minutes at half throttle. Slowly turn the idle screw clockwise until the engine starts to slow, then counterclockwise until it starts to slow. Find the mid point where the engine idles best. Place the cover over the filter and cartridge and secure with the nut.

Adjust the High Speed Mixture

  1. Locate the high speed adjustment screw opposite the idle speed screw. Some carburetors may not have this adjustment option, based on the manufacturer or carburetor's age. Remove the air filter cover, filter and cartridge to access the carburetor.

  2. Start the engine and allow it to run for 5 minutes to warm, then stop the engine. Turn the high speed screw clockwise with a screwdriver until the needle on the end of the screw touches the seat. Turn the screw counterclockwise 1 1/4 turns. Briggs & Stratton cautions that you can damage the tip of the screw if you overtighten it.

  3. Set the throttle to fast and start the mower engine. Turn the high speed screw first clockwise until the engine slows, then counterclockwise until it slows. Locate the center point where the engine idles best. Move the throttle from slow to fast then back to slow to test the adjustment. Place the cartridge, filter and cover on the mower and secure with the nut.

Adjust Carburetor Choke Linkage

  1. Remove the air filter cover, filter and cartridge and locate the choke linkage on the carburetor. Move the throttle to the fast position.

  2. Loosen the bracket holding the casing on the end of the throttle cable in place. Use a screwdriver to loosen the screw on the bracket and release the cable. Do not take the screw completely out.

  3. Move the cable with your fingers until the choke plate on the carburetor closes. Hold the cable in this position and tighten the bracket down against the cable casing to secure it in place. Move the throttle from fast to slow, then to fast again and watch as the choke plate in the carburetor opens and closes.

  4. Things You Will Need

    • Carburetor spray cleaner

    • Screwdriver

    • Gloves

    Warning

    Wear gloves to protect your hands while working.
