1995 Force 40 , SN 0E108215
Timing is good, set the throttle pickup per the manual and adjusted the idle per the manual. Engine idles just fine until any of the controls are used that moves the linkages. Once moved, the engine does not return to idle - it sits up at 1800 to 2000 rpm. Sometimes higher, sometimes lower.
Anyone have any ideas what could cause this?
Could the throttle cam mounting hole be worn, allowing it to move around? Could the rubber bushings on either side of the throttle cam be bad? Could the nut securing the bushings and throttle cam be too loose? Too tight? Or, is it something in the tower shaft?
Any help is appreciated.
Thanks.
