Installation Guide

1. Disconnect the fuel line from the old carburetor and remove the throttle linkage. Carefully unbolt the carburetor from the intake manifold.

3. Position the new carburetor onto the intake manifold, ensuring proper alignment with the mounting holes. Install new mounting bolts and tighten evenly in a cross pattern.
4. Reconnect the throttle linkage and verify smooth movement through the full range of motion. Adjust as needed for proper throttle response.

8. Perform a test run at various throttle settings to ensure proper operation. Check for any fuel leaks or irregular performance.
