Why does my ATV idle high?
A high idling engine on a dirt bike usually indicates a fuel or air pressure problem. When the engine idle suddenly runs high that usually means you’ve sprung an air leak, have a dirty air filter or you’re running bad gas.
How do you adjust the air fuel mixture on an ATV?
Make adjustments 1/2 a turn in either direction to find the smoothest idle speed. Turn the screw counterclockwise and clockwise 1/2 a turn from the middle position and listen to the sound of the idle. Set the screw in the position where the engine’s idle sounds most even and smooth to balance the fuel mixture.
How do you tell if a carburetor is rich or lean?
Typical symptoms of a rich mixture are:

How do you know if your ATV is running lean or rich?
A black dry fluffy colored plug is caused by deposits from a carburetor that is running too rich (too much gas), or excessive idling on some engines. Black smoke coming from the exhaust is a sign of a rich air/fuel mixture.
How do you know if your ATV is running lean?
Lean conditions can be detected by the engine losing power, yet retaining it’s engine speed. For instance, the engine sounds to be accelerating to higher RPMs, yet feels as if it has no power. By looking at the spark plug, a lean condition can be detected by a white, blistered plug.
Are 2 strokes supposed to idle?
Are 2 Stroke Dirt Bikes Supposed To Idle? The simple answer is “Yes”. All dirt bikes, both 2 and 4 stroke and made to be able to idle for a reasonable amount of time. 2 strokes may have a more erratic idle just because of the way the engine works and the timing of each power stroke.
How do you adjust a high and low carburetor?
Locate the two fuel-adjustment screws on the side of the carburetor. One will be labeled “Hi” and the other “Lo.” The “Hi” screw regulates the engine at full throttle and the “Lo” regulates the fuel when the engine is idling.
Why does my bike rev high when I start it?
A motorcycle idles high when it is getting too much of an air and fuel mixture in a low speed or neutral position. This is usually caused by the idle screw on the carburetor being out of adjustment, an out of place throttle handle screw, a bad carburetor throttle spring, or a sticky throttle or throttle cable.
