I am currently trying to get a Super Custom 56 to throttle correctly. I have set up the fast running needle for max revs and now am trying to get the secondary needle adjusted so that it will throttle up smoothly from a fast idle.

What is the correct procedure for doing this? Should I start from it being open X turns and then start closing it down 1/4 turns at a go? or is there a better way of doing this?

Thanks in advance
