Overhauling a Briggs and Stratton carburetor involves removing the carburetor from the engine by disconnecting the spark plug, removing the air cleaner assembly, turning off the fuel valve, disconnecting the anti-afterfire solenoid, unfastening the carburetor mounting bolts and disconnecting the governer springs. Next, the carburetor must be disassembled by removing the fuel bowl, pushing the hinge pin out of the body, removing the float assembly, removing the inlet needle valve and fuel bowl gasket, and removing the idle mixture screw and spring.
Rotating the throttle plate to the closed position and removing the throttle plate screws, the throttle plate, the throttle plate shaft, the foam seal, the choke plate, the choke shaft and all replaceable welch plugs are the next steps. The disassembly process is completed by unscrewing the main jet and emulsion tube and removing the emulsion tube. To continue the overhaul, it is necessary to inspect the carburetor for stubborn grit and other obstructions, and it's also essential to inspect the mixture screws and replace them if they are bent or contain any ridges. Once these tasks are complete, the carburetor can be reassembled and reattached.Learn more about Engine
