Modified 1.5 Inch HS4 SU Carburettor Spindle Kit With O-Rings

As many of you know, Ed D'Arata, Sales Manager for Mini Mania, is an SU Carburetor Whisperer.  He rebuilds all of our SU carbs and tunes many of them on our engine stand to be ready for our customers out-of-the-box. He's created a spindle here for the HS4 carbs with the addition of o-rings - something not available from the factory! This will eliminate vacuum leaks beyond the shaft. The spindles are turned at the machine shop and fitted with o-rings so that they seal perfectly tight in the carb body.

This kit is the same as the WZX1177 kit but with the new modified spindles with o-rings installed. Fits one (1) HS4 carburetor.
