John,
Grasp you throttle shafts and wiggle them. If they wiggle you have worn
shaft bushings which is causing the high idle problem. I currently have
this problem with my 57 TR3. My 63 TR4 had this poblem. In fact every SU
equipped car I've owned has had this problem. Both of them.
You can get over sized shafts but boring out the carb body is best left to
a professional machinist. Jim Taylor - (918) 333 3444 - can rebuild you
carbs for you. (NFI) And there are other professional carb rebuilders out
there.
Good luck
Dave
