Owners can adjust a Briggs and Stratton carburetor by adjusting the idle screw located underneath the air filter. Adjusting the carburetor can help the machinery run smoothly and reduce idling problems.
The majority of carburetors contain idle speed screws. A Phillips head screwdriver often works well for turning these screws and adjusting the carburetor.
Step 1: Turn off the machinery
Users will first need to ensure the machinery is completely turned off. They will then remove the air filter cover and the filter cartridge from position.
Step 2: Adjust the idle speed screw
After locating the idle speed screw below the air filter, users will need to turn it clockwise. Once it is completely turned, it will lightly touch the seat. After it touches the seat, the screw needs to be turned counterclockwise 1 1/2 turns.
Step 3: Let the engine run
After making these adjustments, users should turn on engine and let it run for 5 minutes. This allows it to heat to operating temperature. After 5 minutes, the idle screw should be turned clockwise until the engine begins slowing down and then turned counterclockwise until it slows further. It should then be turned to the halfway point. The owners can then reassemble the filter system.
Step 4: Reassess
If the engine is still idling too low or too high, these adjustments can be made again.Learn More
