4. Operation and Initial Adjustment
After installation, initial adjustments are necessary to ensure proper engine operation. The Holley 0-4412S is wet-flow tested and calibrated from the factory, minimizing the need for extensive tuning.
4.1 എഞ്ചിൻ ആരംഭിക്കുന്നു
- With the manual choke engaged (closed), crank the engine.
- Once the engine starts, gradually open the choke as the engine warms up.
- Allow the engine to reach operating temperature before making final adjustments.
4.2 Idle Speed Adjustment
Locate the idle speed screw on the carburetor. With the engine at operating temperature, turn the screw clockwise to increase idle speed or counter-clockwise to decrease it, aiming for the manufacturer's recommended RPM for your vehicle.
4.3 Idle Mixture Adjustment
The idle mixture screws control the air/fuel ratio at idle. Turn them in (clockwise) until the engine begins to stumble, then back them out (counter-clockwise) until the engine runs smoothly. Repeat for both screws, ensuring they are adjusted equally. This adjustment affects only the idle circuit and not the main fuel curve.
