The SU fitted to the v8 are Hif44 There are two adjustments you can make there is a slow running adjustment screw that adjusts the trhottle lever stop position ( moves the position of the resting stop )
The other is the mixture screw this is on the side of the carb usually covered by an anti tamper plug (usually blue in colour) By screwing this in (to richen) or out you can adjust the mixture datum point.
The fuel flow at any particular throttle opening is controlled by the needle position in the jet tube. The SU is about as good as it gets short of fuel injection

What vehicle and year is the vehicle the engine is in and is it a standard factory fit.Failing that on the carbs you should find a metal tag with a carb spec no.ie.FZX ????LH FZX ????RH
Let me know the details and I'll look up the corresponding needle codes for you.

The carbs and inlet manifold are I believe to be from a P5 or P6, which was fitted to my 2A, prior to changing it to an early 90s factory gold seal recon rangy engine, because of head and block problems.
The metal tag on the carbs are stamped AUD 521 L/R accordingly.
Many thanks for any info.

Many thanks for your help

However I run a V8 in my series 2A with K and N filters using standard
needles as designated for use with the SU carbs fitted.
