- Socket wrench or nut driver set
- Pihdit
- Fuel resistant sealant (optional, for fuel line connections)
Yleiset asennusvaiheet:
- Valmistelu: Ensure the blower is turned off, cool, and the spark plug wire is disconnected. Drain any remaining fuel from the tank.
- Irrota ilmansuodatinkokoonpano: Locate and remove the air filter cover and the air filter element.
- Irrota polttoaineletkut: Carefully disconnect the fuel lines from the carburetor and the fuel tank. Note their routing for correct reinstallation.
- Irrota vanha kaasutin: Unbolt the old carburetor from the engine intake. Pay attention to any gaskets or spacers.
- Inspect and Replace Gasket: Replace the old carburetor gasket with the new one provided in the kit. Ensure it is properly seated to prevent air leaks.
- Asenna uusi kaasutin: Mount the new carburetor, ensuring the gasket is correctly positioned. Secure it with the bolts, tightening them evenly.
- Replace Fuel Lines and Filters: Remove the old fuel lines and filters from the fuel tank. Install the new grommets, fuel lines, and fuel filters. Ensure the fuel lines are routed correctly (supply line to carburetor, return line to tank).
Tip: Gently heating the ends of the fuel lines with a heat gun or hot water can make them more pliable for easier connection to fittings. Avoid open flames near fuel. - Asenna primerpolttimot: If replacing, carefully remove the old primer bulbs and install the new ones.
- Replace Spark Plug: Remove the old spark plug and install the new one, ensuring it is tightened to the manufacturer's specifications (do not overtighten).

Note: Ensure the throttle body does not interfere with other components when the trigger is squeezed, as this can cause the throttle to stick. Adjust as necessary. - Kokoa ilmansuodatin uudelleen: Install the new air filter element (if applicable, not included in this kit but often replaced during tune-ups) and reattach the air filter cover.
