What happens if the float level is too high in this instance?
Incorrect Float Height Symptoms In extreme cases, if the fuel floats are too high, fuel can overflow through the holes in the carb body. The engine will show a lean running condition if the fuel level is too low. This is when the engine hesitates before it accelerates or surges when the throttle is released.
Also, learn more about the carburetor floating needle. The carburetor's float needle controls the fuel flow and maintains the fuel level. The name afloata suggests that it must float in fuel. It is usually made from hollow plastic, metal, or fuel-resistant foam. Some were made of cork back in the past.
How can I tell if my carburetor is stuck?
The engine not being able to idle is a sign that the carburetor floating is sticking. The floating is preventing enough fuel from entering the reservoir. This allows for an engine to idle indefinitely. The carburetor's float is in the closed position and very little fuel is leaking into the reservoir.

How do I know if my carburetor is running rich?
When an engine runs “rich,” it's the exact opposite of running lean, meaning there's excess fuel and not enough air. When this happens, black smoke comes from the exhaust. It's flooded. If there is dirt or debris in the fuel bowl, it can block the needle valve and prevent it from closing.
Why is float level important?
My understanding of what a float does is to control the amount of fuel available (basically make sure it has a constant supply) to the "jets" at any given time and to make sure the carb doesn't have too high a level so it ends up "spilling" out of the carb bowl.
Why is my carb running rich?
If the power valve is too big, it may cause the A/F ratio to run too rich when the engine is under load. A low fuel level can make the A/F ratio run lean, while a fuel level that is too high can make the carburetor run rich or even flood the engine with fuel.

What would cause a carburetor to flood?
The single-most common cause is dirt in the fuel. This will cause flooding because the valve won't seat to shut the fuel off. Therefore, it is important to install fuel filters and to keep the fuel clean. The carburetor itself can cause flooding problems, too--particularly the float valve (needle) and seat.
