- Reconnect cables and fuel line: Carefully reconnect the throttle and choke cables, and the fuel line.
- Install carburetor on the engine: Mount the carburetor back onto the engine, securing it with the mounting bolts.
4. Testing and Adjustment
- Start the engine: Once reassembled, start the engine and allow it to warm up.
- Check for leaks: Inspect for any fuel leaks around the carburetor connections.
