Engine Works offers needle and seat replacements for a variety of Holley carburetors. They are the first stop for the flow of fuel coming into a carburetor—essentially, a basic valve. The seat is typically conical and the needle has a point which seals against the seat to stop fuel from entering the carb at a certain level. This prevents flooding the engine and engine compartment. Needles are available in brass or stainless steel; and seat size options vary from 0.110 in. to 0.150 in.
