Installation Guide

1. Disconnect the fuel line from the existing carburetor and ensure the fuel valve is in the OFF position. Allow the engine to cool completely before proceeding.
2. Remove the air intake cover and filter housing to access the carburetor mounting bolts. Keep all fasteners organized for reassembly.
3. Disconnect the throttle linkage and choke cable from the old carburetor. Take note of their positions for correct reconnection.
4. Unbolt the old carburetor from the intake manifold and carefully remove it. Inspect the mounting gasket and replace if damaged.
5. Clean the intake manifold mating surface thoroughly to ensure a proper seal. Remove any old gasket material or debris.
6. Position the new carburetor assembly onto the intake manifold with a new gasket. Hand-tighten the mounting bolts first, then torque evenly in a cross pattern.
7. Reconnect the throttle linkage and choke cable to the new carburetor in their original positions. Verify smooth operation of both controls.
8. Attach the fuel line securely to the carburetor inlet. Check that all clamps are tight and properly seated.
9. Reinstall the air filter housing and intake cover. Ensure all connections are secure and properly aligned.
10. Turn the fuel valve ON and check for any fuel leaks around connections. Address any leaks immediately before starting the engine.
11. Prime the fuel system by squeezing the primer bulb until firm. Start the engine and allow it to warm up to operating temperature.
12. Adjust idle speed and mixture settings as needed according to manufacturer specifications. Perform a test run to verify proper operation.
