When to make an air fuel mixture adjustment?
Warm up the engine to normal operating temperature by letting it idle for about 5 minutes. Keep the engine running after it warms up. Always make air fuel mixture screw adjustments with a warm engine and the engine running, so you can listen to how the adjustments affect the engine’s idle speed.
What happens when you tighten the fuel mixture screw?
Tightening the screw is also called making the fuel mixture leaner, which lowers the RPMs at which the engine idles. Running a lean fuel mixture makes the engine run with less fuel than it needs to run efficiently. This can damage an engine because there is more friction between moving parts and the engine operates at a higher temperature.

What happens when you loosen the fuel mixture screw?
1 Loosening the screw strengthens the air and fuel mixture and increases the amount of fuel flowing to the engine. 2 Loosening the screw is also called making the fuel mixture richer, which increases the RPMs at which the engine idles. 3 Running a rich fuel mixture causes the engine to run with more fuel than it needs to operate efficiently. …
How to adjust the air / fuel mixture in a scooter?
Start your scooter and let it run for 10 minutes to get the engine up to operating temperature and allow the auto-choke (enricher) to close completely. If the carburetor is so far out of adjustment that the scooter won’t start, turn the air/fuel mixture screw all the way in until it stops, then turn it back out about 2 turns as a baseline setting.
What’s the best way to adjust the fuel mixture?
Set the two air/fuel mixture screws to a baseline point so that the mixture can be adjusted while the engine is idling. To set the baseline point, turn each screw in a clockwise direction with a flathead screwdriver until each screw seats, then back both screws out 1-1/2 turns.

When to stop turning the air fuel mixture screw?
Listen to the engine’s idle sound and stop turning the screw when it starts making a rough rising and falling sound instead of its normal idling sound. Tightening the screw weakens the air and fuel mixture and decreases the amount of fuel flowing to the engine.
