Carburetor Maintenance
Regular carburetor maintenance is a great way to save yourself money, headaches, and hassle down the road. Most carburetor problems are caused by blockages from dirt, varnish, and gasoline deposits.
Cleaning the main fuel jet with carburetor cleaner and compressed air can help blow out loosened debris. Carburetor cleaner dissolves deposits in your carburetor and choke, reducing your need for maintenance, repair, and downtime, while improving starting for all 2-cycle and 4-cycle engines.
You can clean the carburetor by locating the fuel bowl nut and using carburetor cleaner to dissolve any deposits. After cleaning, it's a good idea to adjust the idle speed and mixture, especially for float-type carburetors.
Carburetor adjustments can only be made on older, non-EPA regulated carburetors, and typically involve turning the high-speed needle valve 1-1/2 turns open from the seat, and the idle valve 1-1/4 turns open from the seat.
