ABSTRACT:
A valve assembly is provided for controlling the flow of fuel to the fuel chamber of a carburetor. The valve assembly includes a housing and a needle. The housing includes a side wall defining an inlet, an outlet in fluid communication with the inlet, and an interior region between the inlet and outlet. The needle is received in the interior region of the housing for movement therein between a closed position blocking the flow of fuel between the inlet and the outlet and an open position allowing the flow of fuel between the inlet and the outlet. The needle includes a post and a skirt fixed to the post. The skirt extends outwardly from the post and cooperates with the side wall to restrict the flow of fuel therebetween dampening the movement of the needle relative to the housing so that the needle moves with the housing when the housing vibrates in response to the operation of the engine.
