Revitalize your STIHL string trimmer with this all-in-one carburetor and tune-up kit. A professional-grade solution designed to restore reliable starting, smooth operation, and full power to your FS series trimmer by replacing its most critical fuel and ignition components. Comprehensive Kit for Common Performance Problems Over time, the carburetor in your STIHL trimmer can become clogged with stale fuel deposits, its diaphragms can harden, and its internal passages can wear. Simultaneously, the spark plug fouls and the fuel filter becomes restricted. This leads to a cascade of frustrating issues. Instead of attempting to clean or rebuild an old carburetor with uncertain results, this kit provides a complete, new assembly along with other vital wear items. Replacing them together ensures all components of the fuel and ignition system are in like-new condition, addressing multiple potential failure points at once. What's Included and Its Function 1. Complete Carburetor Assembly (WT-45 Type): The heart of the kit. A fully assembled replacement carburetor, pre-set with factory baseline adjustments. It includes the fuel pump, metering, and idle circuits ready to install. 2. Spark Plug: A new spark plug ensures a strong, consistent spark for reliable ignition, which is crucial for easy starting and efficient combustion. 3. Fuel Filter: A clean inline fuel filter prevents dirt and debris from the fuel tank from entering and damaging the new carburetor. 4. Oil Pipe / Impulse Line: This critical hose connects the crankcase to the carburetor's fuel pump diaphragm. A cracked or leaking impulse line will prevent the carburetor from pumping fuel. 5. Gaskets and Seals: Includes intake manifold gaskets and other necessary seals to ensure airtight connections between the carburetor, engine block, and air filter, preventing vacuum leaks that cause poor running. 6. Hardware (Clip, Knob, Grommet): Essential mounting clips, the adjustment knob, and protective grommets for a complete, secure installation.

You will now have clear access to the carburetor. 2. Disconnect Linkages: Carefully note the positions of all linkages. Remove the throttle trigger linkage, the choke linkage (if separate), and the fuel primer bulb lines (if equipped). 3. Disconnect Fuel Lines: Pinch and remove the fuel lines from the old carburetor. Note which line goes to the fuel tank (supply) and which is the return (if applicable). The impulse line is usually a smaller diameter. 4. Remove Old Carburetor: Unscrew the two nuts or bolts securing the carburetor to the intake manifold. Remove the old carburetor and the old gaskets. 5. Install New Gaskets & Carburetor: Place the new gasket(s) on the intake manifold. Position the new carburetor and secure it with the original hardware. Do not over-tighten. 6.

Connect the new spark plug and set the gap if required. 7. Final Steps & Adjustment: Reinstall the air filter and cover. Reconnect the spark plug wire. You will likely need to adjust the idle speed (LA) and mixture (H & L) screws on the new carburetor. Refer to your STIHL trimmer's manual for baseline settings and final tuning procedure.
