Enstriksyon Operasyon
After installation, the carburetor may require minor adjustments for optimal performance. This carburetor is designed to be a high-quality replacement and may come pre-adjusted for common applications.
Inisyal Start-up
- Ensure the fuel tank is filled with the correct fuel mixture (if applicable for 2-stroke engines).
- Prime the carburetor if it has a primer bulb, until fuel is visible.
- Set the choke to the "full choke" position.
- Start the engine according to your equipment's manufacturer instructions.
- Once the engine fires or attempts to start, move the choke to the "half choke" or "run" position.
- Allow the engine to warm up for a few minutes before operating under load.
Carburetor Adjustment (if necessary)
Most small engine carburetors have two main adjustment screws: High-speed (H) and Low-speed (L) mixture screws, and an idle speed screw (T).
- Vitès ralenti (T): Adjusts the engine's RPM at idle. Turn clockwise to increase idle speed, counter-clockwise to decrease.
- Low-Speed Mixture (L): Controls the fuel-air mixture at idle and low RPMs. Adjust in small increments (1/8 turn) to achieve smooth idle without bogging down.
- High-Speed Mixture (H): Controls the fuel-air mixture at high RPMs. Adjust in small increments to achieve maximum power without sputtering or overheating.
Nòt: Carburetor tuning can be complex. If you are unsure, consult a qualified technician or refer to specific tuning guides for your equipment model.
Antretyen
Proper maintenance ensures the longevity and performance of your carburetor and equipment.
- Kalite gaz: Always use fresh, clean fuel. Stale or contaminated fuel is a primary cause of carburetor issues.
- Filtè gaz: Regularly inspect and replace the in-tank fuel filter to prevent debris from entering the carburetor.
- Filtè lè: Keep the air filter clean and replace it as recommended by your equipment manufacturer. A dirty air filter can cause rich fuel mixtures and poor performance.
- Depo: Before long-term storage, drain the fuel system or use a fuel stabilizer to prevent gum and varnish buildup in the carburetor.
