I'm assuming that you are talking about adjusting the fuel level by adjusting the height of the pickup tube inside the tank. If that tube is too high it won't pick up the fuel, if it's too low the alcohol will over flow the top of the wick holding tubes under the engine. This latter condition will be evidenced by starting fires on the ties under the engine, particularly when the engine is at rest.
