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.

Question:
If my existing shaft bushings are worn, will these seal the vacuum leaks? Or will I have to rebush to use these?
Answer:
Most of the time the shafts are what wear and the bushings are ok, but you won't really know until you try one. We do rebushing if you need that done, just give us a call.

Question:
Do you stock/carry replacement parts for HS4 carburetors? Needing (2) red springs part # AUC4387 and a pair of oversize throttle shafts part # WZX1177RP.
Answer:
The red springs we have, but would have to see if we could find a source for the shafts. We do however have the new o-ring style shafts in stock that we use on all of the carbs we rebuild as long as the bushings are not totally shot, they work very well sealing the shafts.  WZX1177A. You might give them a try.

Question:
Does the carb need to be modified to use this spindle, or is it a direct replacement?

No modification to the carb is required.

Happy Motoring!
