Fuel Delivery Issue: Ensure unobstructed fuel flow from tank to carburetor. Check for kinks, blockages, or foreign debris in fuel lines. 2. Low Idle Speed: New carburetors are calibrated for factory-standard engine parameters. Older engines may require slight idle speed adjustment due to wear. Use the idle adjustment screw (clockwise 1–2 turns) to increase idle speed as needed. 3. Clogged Vacuum Port: A blocked vacuum port can cause stalling. Verify the vacuum port is clear after installation.
