Step 6: Attaching The Carburetor & Air Cleaner Assembly. Step 1: Removing the Carburetor. Disconnect the spark plug lead and secure it away from the spark plug. Then, remove the air cleaner assembly. Turn off the fuel valve at the base of the fuel tank.
If your engine does not contain a fuel valve, use a fuel line clamp to prevent fuel from draining out of the tank while the carburetor is disconnected from the engine. Some carburetors contain an electrical device at the base of the fuel bowl to control afterfire. Disconnect the device, known as an anti- afterfire solenoid, by removing the wire connector from the solenoid's receptacle. With the carburetor still connected to the governor, unfasten the carburetor mounting bolts. If a connecting pipe joins the carburetor to the engine block, first remove the pipe mounting bolts.
Then, disconnect the carburetor from the pipe by removing the nuts and sliding the carburetor off the studs. Sketch the governor spring positions before disconnecting them to simplify reattachment.
Then, disconnect the governor springs and remove the carburetor, taking special care not to bend or stretch links, springs or control levers. Step 2: Disassembling A Float- Type Carburetor. Your carburetor contains a small amount of fuel.
Prepare a clean bowl to catch dripping fuel and store small parts. During disassembly, inspect the bowl for dirt and debris to determine the condition of your carburetor. Remove the fuel bowl from the carburetor body. The fuel bowl may be attached with either a bolt or the high- speed mixture screw. Push the hinge pin out of the carburetor body with a small pin or pin punch.
Take care to tap only the pin to avoid damaging the carburetor body. Maxkon Vacuum Box Manual. Remove the float assembly, inlet needle valve and fuel bowl gasket. If your carburetor contains an idle mixture screw, remove it along with the spring.

Then, remove the choke plate and choke shaft and felt or foam washer in the same manner. Use your carburetor repair kit to identify replaceable welch plugs. These seals cover openings in the carburetor left over from machining. Insert a sharpened 5/3. Then, unscrew the emulsion tube; it may be screwed in tight.
A carburetor screwdriver is the best tool for the job. It's designed to fit the slot in the head or the emulsion tube so that you won't damage the threads inside the pedestal of the tube itself as you loosen it. Remove the emulsion tube. Step 3: Inspecting the Carburetor.
Soak metal and plastic carburetor parts in all- purpose parts cleaner for no more than 1. Or, while wearing safety glasses, spray the parts with carburetor cleaner. Then, wipe away solvent and other residue thoroughly using a clean cloth. Never use wire or tools because they can damage or further obstruct plugged openings. Inspect all components and use additional carburetor cleaner to loosen stubborn grit and to clear obstructions. Replace any parts that are damaged or permanently clogged.
Step 4: Inspecting Air- Fuel Mixture Screws. Brass mixture screws control the air- fuel mixture at high speed and at idle.
How to Set a Briggs & Stratton Carburetor. Turn off the engine and allow it ample time to cool fully. Loosen the large set screw on top of the air filter with a flathead screwdriver and remove the air filter from the carburetor. Locate the idle adjustment screw on the side of the carburetor. Gently turn the screw clockwise with a flathead screwdriver until the valve touches the seat. Then, back the screw off counterclockwise one- and- a- half turns.
Look on the opposite side of the carburetor, for the high- speed adjustment screw - - if your carburetor has one. Gently turn the screw clockwise until the valve touches the seat, then back this screw off one- and- a- half turns as well. Check to see if your engine has a large bowl on the bottom side of the carburetor that houses the float. If so, it will have a single screw on the bottom of the bowl.
Turn the screw clockwise until it stops turning, then back it off one- and- a- half turns. Replace the air filter on top of the carburetor and secure it by tightening the screw in the center of the air filter. Start the engine and let it half- throttle for about five minutes to warm up. Then, slowly turn the idle adjustment screw - - which you adjusted in Step 3 - - clockwise until the engine begins to slow. Note the position of the screw and then begin turning the screw counterclockwise.
The engine will normalize, then eventually will begin to slow once again. Note the position where it begins to slow a second time and rotate the screw clockwise to a point halfway between the two positions where the engine began to slow.
You have now fine- tuned the idle adjustment. Increase the throttle to full speed. Repeat the adjustments you made on the idle screw on the high- speed screw - - on the opposite side of the carburetor from the idle screw. Test the engine under varying workloads.
If the engine runs roughly under any conditions, adjust the idle or high- speed screw to fine- tune the adjustments.
