Carburetor

[torpedo]

A few weeks ago I had to get a new carb so I just got a replacement for my old one (a generic Holley 1850). The guy that did it shortened the choke cable a little bit, on the old one it wouldn't open quite all the way so he put a spring on it to open it once you pushed it back in. On the new one you literally can't shut it by pulling the cable in the cab, you have to open the hood and push it shut. So I took the spring off and all it did was make it easy to shut but once it was shut it wouldn't open at all. I've tried different sized springs (ones I had left over from when I had to replace the throttle spring) but that didn't help. The cable isn't bunched up anywhere and I'm completely stuck on how to get it to open and shut smoothly.
