I'm having issues with the choke on my samurai so I was studying the fsm for 88 samurai to try and understand how the choke functions. Anyway while reading I noticed the fast idle adjustment procedure, I was under the impression that there is no fast idle adjustment other than bending the arm that contacts the thermowax element. In the fsm it has a fast idle adjustment screw and outlines how to do the adjustment using this screw.

I haven't messed with it yet but was wondering why I've read on the forums that there is no fast idle screw on the stock samurai carb?
