- Wear appropriate personal protective equipment, including gloves and eye protection.
- Handle gasoline and LPG with extreme care. Refer to your generator's manual for additional fuel handling safety.
3. Setup and Installation
3.1 Pre-installation Checks
- Verify that the new carburetor matches the specifications of your generator model (Pulsar 6580/5500 Watts HD6580B).
- Gather necessary tools: wrenches, screwdrivers, pliers, and a clean cloth.
- Ensure the generator's fuel tank is empty or the fuel valve is closed, and the LPG tank is disconnected.
3.2 Installation Steps
- Remove Air Filter Assembly: Loosen clamps and bolts to remove the air filter housing and element.
- Disconnect Fuel Lines: Carefully disconnect the gasoline fuel line from the old carburetor. If applicable, disconnect the LPG line. Be prepared for minor fuel spills.
- Disconnect Linkages: Detach the throttle and choke linkages from the old carburetor. Note their positions for reassembly.
- Remove Old Carburetor: Unbolt the old carburetor from the engine manifold. Remove any gaskets.
- Install New Carburetor: Place new gaskets (if supplied) on the manifold studs. Mount the new dual fuel carburetor, ensuring it seats correctly. Secure with bolts, tightening evenly.
- Reconnect Linkages: Reattach the throttle and choke linkages to the new carburetor. Verify smooth operation.
- Reconnect Fuel Lines: Connect the gasoline fuel line securely. For LPG operation, connect the LPG hose from the regulator to the carburetor's LPG inlet. Ensure all connections are tight to prevent leaks.
- Reinstall Air Filter Assembly: Reattach the air filter housing and element.
- Leak Check: Before starting, inspect all fuel connections for leaks.
4. Operating Instructions
4.1 Fuel Selection
This carburetor allows operation on either gasoline or LPG. Do not attempt to run on both fuels simultaneously.
- For Gasoline Operation: Ensure the LPG supply is off and disconnected. Open the gasoline fuel valve.
- For LPG Operation: Ensure the gasoline fuel valve is closed. Connect the LPG tank and open its valve.
4.2 Starting the Generator
Refer to your generator's specific starting procedure. General steps include:
- Ensure the generator is on a level surface.
- Select your desired fuel type (Gasoline or LPG) as described in Section 4.1.
- Set the choke lever to the "CHOKE" position (cold start).
- Pull the recoil starter handle firmly or engage the electric start until the engine fires.
- Once the engine starts, gradually move the choke lever to the "RUN" position.
- Allow the engine to warm up for a few minutes before applying load.
5. Maintenance
Regular maintenance ensures optimal performance and longevity of your carburetor.
- Carburetor Cleaning: Periodically inspect the carburetor for dirt or debris. If necessary, clean with a carburetor cleaner spray. Avoid using wire or hard objects that could damage jets.
- Fuel Line Inspection: Check gasoline and LPG fuel lines for cracks, leaks, or deterioration. Replace damaged lines immediately.
- Air Filter: Ensure the air filter is clean and free of obstructions. A dirty air filter can affect carburetor performance. Refer to your generator manual for air filter maintenance.
- Storage: If storing the generator for an extended period, drain the gasoline from the fuel tank and carburetor bowl to prevent gumming. Disconnect the LPG tank.
