Operating and Initial Adjustments
While this carburetor is pre-set for general use, minor adjustments may be necessary for optimal performance with your specific engine. Refer to your STIHL equipment's original instruction manual for detailed carburetor adjustment procedures.
General Adjustment Guidelines:
- High-Speed (H) Screw: Controls the fuel mixture at high engine speeds. Turning clockwise (in) leans the mixture; counter-clockwise (out) enriches it. Adjust for maximum engine speed without sputtering.
- Low-Speed (L) Screw: Controls the fuel mixture at low engine speeds and idle. Adjust for smooth idling and good acceleration.
- Idle Speed (T) Screw: Adjusts the engine's idle RPM. Turn clockwise to increase idle speed, counter-clockwise to decrease.
Маанилүү: Always make small adjustments (e.g., 1/8 to 1/4 turn) and test the engine's response. Incorrect adjustments can lead to engine damage or poor performance. If you are unsure, consult a qualified service technician.
Техникалык тейлөө
Regular maintenance helps ensure the longevity and performance of your carburetor and equipment.
- Күйүүчү майдын сапаты: Always use fresh, clean fuel mixed according to your STIHL equipment's specifications. Stale or contaminated fuel is a primary cause of carburetor issues.

- Сактагыч: Before long-term storage, drain the fuel system or use a fuel stabilizer to prevent fuel degradation and gumming in the carburetor. Run the engine until it runs out of fuel to ensure the carburetor is dry.
- Тазалоо: If performance issues arise, the carburetor may require cleaning. This typically involves disassembling the carburetor, cleaning passages with carburetor cleaner, and replacing gaskets. This procedure should only be performed by individuals with mechanical experience.
