Description

15B-325 Tillotson OEM Throttle Cable Set Screw


Secures Throttle Cable in Swivel Barrel | Genuine Tillotson Replacement Part

The 15B-325 Tillotson Throttle Cable Set Screw is an OEM replacement screw designed to secure the throttle cable into the swivel barrel on the throttle shaft. This tiny but crucial component ensures your throttle cable stays firmly in place, allowing for precise throttle response and consistent operation — especially in high-vibration environments like kart racing or small engine performance applications.


Whether you're installing a new throttle cable or restoring a worn carburetor linkage, this set screw is essential for keeping your throttle system tight and responsive.


Key Features:

  • OEM Part Number: 15B-325
  • Designed to fit the swivel barrel on the throttle shaft
  • Holds the throttle cable securely in place
  • Prevents cable slippage during operation
  • Ideal for racing, small engine, and high-performance setups
  • Durable steel construction with precision threading


Applications:

  • Used on Tillotson HL, HR, HW, and other series with a throttle shaft swivel barrel
  • Common in 2-cycle and 4-cycle racing engines, go-karts, and performance applications
  • Compatible with standard throttle cable setups requiring barrel locks


Installation Tip:

Apply a small amount of blue thread locker if the screw is exposed to high vibration or extreme conditions. Be careful not to overtighten — the set screw only needs to secure the cable, not crush it.
