throttle adjust on an 06 600 RMK

[knee deep in it]

the throttle lever is a little loose. When the sled is cold, you have to keep your hand on the throttle or it will die. You can even rest a glove on it and that will work.

Seems to me that if I tighten the throttle cable, it will make it worse. It is almost like the throttle safety switch is what needs adjusting.

Any ideas before I go tighten the throttle cable.
