1. Safety First: Before you start any repair, make sure that the engine is turned off, cooled down, and disconnected from the power source.
2. Locate the Primer Bulb: The primer bulb is usually located near the carburetor on the engine.
3. Disconnect the Fuel Line: Use a pair of pliers to pinch off or loosen the fuel line clamp to disconnect it from the primer bulb.
4. Remove the Primer Bulb: Gently squeeze and pull the old primer bulb off the engine's fuel supply port.
5. Clean the Primer Bulb Seat: Clean the surface where the primer bulb was seated to ensure a proper seal with the new bulb.
6. Install the New Primer Bulb: Align the new primer bulb's inlet and outlet ports with the corresponding ports on the engine and fuel line.
7. Reconnect the Fuel Line: Reattach the fuel line to the primer bulb by pressing it firmly onto the inlet port and securing it with the clamp.
8. Test the Primer Bulb: Press the new primer bulb several times to ensure fuel flows through the system. Check for any leaks or issues with the fuel flow.
9. Start the Engine: Start the engine to check that the primer bulb works correctly and that there are no fuel leaks.
10. Re-adjust Clamp if Necessary: If you notice any fuel leaks, re-adjust the fuel line clamp to ensure a tight fit.
Remember, while replacing the primer bulb is relatively straightforward, if you encounter any issues or discomfort working on small engine components, it's best to seek help from a professional.
