$27.19

  • Precise control: This 34-7 needle and seat hardware kit can control the fuel flow into the float chamber based on the position of the float. When the fuel reaches the preset level, the float can push the needle valve to close the valve seat and stop the flow of fuel; When the fuel level drops, the needle valve opens, allowing fuel to flow in and achieving precise control of the fuel level in the float chamber of the carburetor.
  • Good performance: The locking screw and adjusting nut of our 34-7 needle and seat hardware kit are designed to work together. Once you find the perfect oil level through the adjusting nut, it can be securely locked, solving the problem of setting deviation caused by high-intensity engine vibration. Ensure that every parameter you adjust is maintained by this reliable needle and seat kit.
  • Durable Material: The core components of this 34-7 needle and seat hardware kit are crafted from sturdy brass material, providing excellent durability and resistance to corrosion and high temperature environmental tests, ensuring a solid foundation for the long-lasting, stable, and reliable operation of your for Holley carbureter.
  • Easy Installation: The installation process of this seat nut kit is very simple. Insert the needle valve seat into the top of the float chamber, then place a larger gray washer on the surface of the float chamber, screw on the silver adjusting nut, then fit the smaller gray washer onto the gold locking screw, and screw it into the top of the adjusting nut.
  • Alternative worry free: Carburetor parts include two locking screws, two adjusting nuts, two nut sealing washers, two nut sealing washers, and two O-rings, providing you with an additional set of backup solutions to solve maintenance problems in one stop.

34-7 needle and seat hardware kit is a high-precision maintenance component used for carburetor fuel control. The core of this product is an externally adjustable design, which allows precise control of the fuel level through adjusting the nut without the need to disassemble the float chamber. It is fixed and set by locking screws to ensure stable parameters under engine vibration.
The 34-7 needle and seal hardware kit is made of brass material to ensure corrosion resistance and long-term reliability. It has good corrosion resistance and can maintain good performance even in high-temperature environments. At the same time, the installation process of the Holly needle and seal is also very simple. Insert the needle valve seat into the hole at the top of the float chamber. Next, place the larger gray washer on the surface of the float chamber, screw on the silver adjusting nut, then place the smaller gray washer on the gold locking screw, and gently screw it into the top of the adjusting nut.
This needle and seat is compatible with the for Holley 4150 M2300 4160 R5000 carburetor.
