What is the function of a needle and seat in a carburetor?

The needle and seat assembly controls the fuel level in the carburetor's float bowl. The needle rests on the seat to stop fuel flow when the bowl is full and lifts off to allow fuel in when the level drops.

Why would I need a larger diameter needle and seat like the .145 inch size?

A larger diameter seat, like the .145 inch size in this kit, allows for a higher fuel flow rate into the carburetor. This can be helpful for modified engines that require more fuel than a stock setup.

Is this part approved for use in California?

No, this part is not CARB approved and cannot be shipped to California due to emissions regulations.

Product Details

Edelbrock has been a name in performance parts for a long time, and this Needle and Seat Kit is part of their carburetor offerings. This kit is specifically for Q-Jet carburetors and includes a .145 inch diameter seat assembly. This size is designed for higher flow capacity, which can be beneficial for engines that need more fuel delivery than stock.

The needle and seat work together to control the fuel level inside your carburetor's float bowl. When the fuel level drops, the needle lifts off the seat, allowing fuel to enter. As the fuel level rises, the needle is pushed back onto the seat, stopping the flow. Having a .145 inch seat means it can let more fuel in at once compared to a smaller opening. This particular kit is the same one used in Edelbrock's own PN 1910 carburetor, suggesting it's a well-matched component for their performance applications.
