I have searched high and low throughout this forum as well as all other resources I know of and have not found the solution to my problem. There were a couple other threads posted on Pirate 4x4 with no response or resolution so I know I'm not the only one...

I have a 1987 22R with the stock Aisian carburetor. I rebuilt the carb recently and as I was putting it back together, I got the throttle linkage on the throttle body rotated the wrong way. Thanks to this amazing collection of images at pirate4x4 I was able to get the linkage assembled properly. Or so I thought.

Every since the rebuild my fast idle doesn't come on at all. The fast idle cam has a torsion spring that seems as though it should force the cam down onto the throttle arm so that if the choke is closed, the cam holds the throttle slightly open. This spring is completely loose and the way I have the linkage assembled, it is impossible for the spring to ever be anything but slack due to the limit on relative rotation between the cam and the plate arm that rotates within the cam's cutout.


Why is this spring loose? Based on every picture I've seen, I have the thing assembled correctly. And I cannot wind the spring around another revolution. It's too tight.
