Description
A high-flow needle-and-seat assembly comes with installation hardware for most Holley performance carburetors. Its adjustable design uses a 0.110-inch seat and Viton sealing material.
Holley offers a number of needle and seat assemblies for its Carburetors. The configuration of the needle and seat assembly and its seat size depend on Carburetor application, CFM size and type of fuel bowl used. Operation is simple. Needle movement is controlled by a metal tang on the float arm. Upward movement of the float causes the needle to close the seat, downward float movement causes the needle to open the seat. Seat size determines how much fuel can flow at a certain pressure. A bigger seat size will flow more fuel, a smaller seat size will flow less fuel at a given pressure. Most Holley performance Carburetors come equipped with a Viton® tipped needle. The Viton® needle design is resistant to dirt and conforms nicely to the shape of the seat for superior sealing.
