Tech Notes
This is the Hi-Speed Needle Valve for the Tower 61 and 75 Engines.
This is located on the remote needle assembly and
adjusts fuel flow to the carburetor.


Knurled needle top for adjustment by fingers
O-rings are pre-installed


One Hi-Speed Needle
Two Black O-rings (pre-installed)


Assembly onto the needle valve assembly


Length: 34.5mm
Knurled portion length: 10mm
Knurled portion diameter: 6.9mm
Hole diameter at the end of needle: 1.7mm


This needle simply threads into the Hi-Speed Needle valve assembly
There is also a set screw pre-installed into the knurled part of the
needle, and a hole at the end of the needle so a piece of wire
or hex wrench can be used as a needle valve extension. The set
screw requires a 1.5mm hex wrench to tighten it.
