Been away for a while , and thought I would close out this thread by letting everyone know thanks to all of you, my problems have been resolved. Regarding the click adjustment that I couldn't turn, I took off the cover, put a screwdriver on it and turned it one click back and forth, evidently it was stuck. Put the cover back on and using the split linkage test, I was able to adjust and get an acceptable idle.
Regarding the hot start problem, I disconnected the ground side of TTS switch and wired a momentary switch to control it manually as suggested and that solved the hot start problem. Another problem I had that i never posted was an intermittent brake hang up. Booster and Master had been replaced for vacuum and fluid leaking problems. Found the RF Caliper hanging up, replaced that, but still had the same problem.Finally found the brake kinkage pivot below the booster was sticking. Took it all apart cleaned and lubricated that and problem was solved.
Without going into a long story as to why, I'm going to be sending this car to my Nephew in California, If anyone can recommend a reputable shop to service / repair this car when needed, It would be greatly appreciated. This 64 230 SL will be living in the Malibu,Thousand Oaks, Agoura Hills,Calabasas area.
Again, thank you all for sharing your knowledge and expertise.
I will also be posting my request for a shop recommendation on the discussion board
