I have been looking on-line at a set of twin HS4 Su's for an MGB GT. I have a classic mini 1275 and was wandering what type of float bowel I would need and the angle would be adjacent to the angle of the carburettor body? I will also be replacing the jet sets, damper springs and linkages as the MGB manifold is longer than that of the classic mini. Any advice would be much appreciated.

Hey Joe, I was informed a Weber 32/36 setup would not work as well as SU's on my 2.0l Volvo engine. The car came with the Weber, and I was sold a pair of SU's to replace them. We rebuilt the motor and added the cam, porting and O/S piston setup. Question is do I rebuild the SU's or go with the Weber? Are the SU's a better carb setup for a mod motor?

Hi Joe, I’ve replaced the needle assembly in my left hs2 classic mini carb however it occasionally leaks after hard acceleration. The float seems to be fine (the plastic non adjustable type) what could be the issue? The right carb has not leaked once as uses the same brand of new needle.
