Fast idle/start lever

I just bought a 1987 cajun bass tactics boat with a 1983 70hp Evinrude & I'm having issues with it. Raising the fast idle lever will bring the engine linkage off of idle set screw & advance timing, pushing it back down doesn't return it to idle or retard the throttle. Is the lever suppose to return it to idle or does the spring loaded linkage on the engine return it to the idle stop?
 
Adjust the trunnion on the cable at the motor.-----Or perhaps something is broken in the control box.-----Easy to check by splitting the control box.

I split the control box & found the fast idle lever link broken. Replaced it, before it wasn't working. Now it'll increase engine linkage off of idle with lever up, but doesn't reset the linkage when pushed back down.

Did you push/pull the throttle cable by hand when you had the control box apart? The cable should move smoothly and easily by hand, and if not you likely have a corroded or broken cable that needs replaced.
