Holley Adjustable Needle and Seat - 0.097 Orifice - Viton - Holley Carburetors

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(R)-tipped needle. The Viton(R) needle design is resistant to dirt and conforms nicely to the shape of the seat for superior sealing. For this reason it is not recommended to use a steel needle, except for racing.

Holley has been the undisputed leader in fuel systems for over 100 years. Holley carburetors powered every NASCAR Cup team and nearly every NHRA Pro-Stock champion for four decades. Now, Holley EFI products power these cars and are dominating the performance world. Holley products for GM's popular LS engine are dominating the LS scene as well. Holley's products also include performance fuel pumps, intake manifolds and engine dress-up products for street performance, race and marine applications. As a single solution or partnered with products from other Holley companies we can give you the edge you need over the competition!
