Installation Guide

  1. Safety First: Ensure the engine is completely cool and disconnect the battery negative terminal.
  2. Fuel Supply: Shut off the fuel valve. Place a rag or container under the fuel line connection and carefully disconnect it from the carburetor.
  3. Linkages: Detach the throttle and choke control linkages. Take a photo or note their positions for accurate reassembly.
  4. Remove Old Carburetor: Unscrew the mounting nuts or bolts that secure the carburetor to the intake manifold and remove the old unit.
  5. Clean Surface: Thoroughly clean the engine’s intake manifold surface, ensuring all old gasket residue is removed for a proper seal.
  6. Position Gasket: Place the new gasket onto the manifold, aligning it with the mounting studs.
  7. Install New Carburetor: Mount the new carburetor assembly onto the studs, ensuring it sits flush against the new gasket.
  8. Secure Assembly: Hand-tighten the mounting nuts/bolts, then torque them evenly in a crisscross pattern to the manufacturer-specified value. Do not overtighten.
  9. Reconnect: Reattach the throttle and choke linkages, followed by the fuel line.
  10. Check for Leaks: Turn the fuel supply on and carefully inspect for any fuel leaks around the connection.
  11. Final Steps: Reconnect the battery terminal. Start the engine in a well-ventilated area and allow it to warm up.
  12. Adjust Idle: If necessary, adjust the idle speed screw to achieve a smooth, stable idle per your engine’s service manual.
