QuoteJust my thoughts.I do not know the specifics if the throttle shaft is bushed (I would assume and hope so) or is just turning in the body itself on your FI set up and it is the reason I suggested putting a small return spring on the accelerator pedal, this was the solution that Rover came up with on the MPI's the SPI's did not have this set up.The problem I have run into several times over the years working on SU's is when owners had idle problems and decided to use a bigger spring to solve it on the Carb end, this resulted in increased wear mainly noticeable on HS2 and HS4 set ups.Volvo had a mechanical linkage on their twin carbed 4 cylinders with way overrated return springs that would wear a set of carbs out in less than 30k.The "bird cage" spring you are using is the same as BMC used in a set of 3 on Mini Coopers and S's and is not a powerful spring but will wear out a set of HS2's.I am not saying it will wear out your throttle shaft like I said I don't know the specifics but I myself would rather risk a cheap throttle pedal assembly than that expensive FI set up.The only other thing I would look into is getting the cable to run straight from the bulkhead instead of the 90 degree turn it currently has.Great build btw and Good luck I hope you get it sorted.
