Lost Kickdown

Thanks, I have the Bouchillon cable kit. I have had the mechanical, Lokar, now BPE. For my setup BPE has been the best. I did have full throttle kickdown until I changed the spring, without changing the linkage the kickdown changed. Now if I shorten the travel enough to get kickdown, I only get half throttle at the carb. I tried moving the pin on the carb linkage to make the kickdown lever ratio lower it still didn't help.
