Obsługa i regulacja
After installation, the carburetor may require minor adjustments for optimal engine performance. Refer to your blower's original manual for precise adjustment procedures.
- Pierwsze uruchomienie: Fill the fuel tank with fresh, properly mixed fuel (if applicable for 2-stroke engines). Reconnect the spark plug wire. Follow your blower's starting procedure.
- Regulacja gaźnika: Many carburetors have high-speed (H) and low-speed (L) adjustment screws. If the engine runs poorly, these may need fine-tuning. A common starting point for adjustment is to turn both screws gently clockwise until they seat, then back them out 1 to 1.5 turns counter-clockwise. Adjust in small increments (1/8 turn) until the engine runs smoothly and accelerates properly.
- Typ paliwa: To prolong the life of your small engine and carburetor, avoid using fuel containing ethanol, especially if the equipment is stored for extended periods. Ethanol can cause damage to fuel system components.

- Filtr paliwa: Inspect and replace the fuel filter periodically (e.g., annually or every 50 hours of operation) to prevent contaminants from reaching the carburetor.
- Przewody paliwowe: Check fuel lines for cracks, hardening, or leaks. Replace them if any damage is observed.
- Świeca: Inspect the spark plug for wear or fouling. Replace it as part of routine maintenance or if starting issues occur.

- Magazynowanie paliwa: When storing the blower for extended periods, drain the fuel tank or use a fuel stabilizer to prevent fuel degradation and carburetor issues.
