I inherited my father in-law's Exmark Metro 26 self propelled walk behind with Kawasaki 4.5/5 hp FJ180V engine. I have adjusted the governor per service manual.
(Turned top of gov arm ccw and gov shaft ccw and locked). Prior to start, the throttle butterfly sits at half throttle position (not closed to idle stop). The throttle control at handle works fine and moves easily and as it should from... STOP (cutoff circuit at control assy is grounded), to MID throttle, to FULL throttle and all the way to CHOKE (WOT). The governor arm/shaft moves freely (in about 10 degree arc). The Control assembly moves freely via the cable control on handle, and all springs/arms are connected properly. Still, the throttle butterfly remains at half throttle static prior to cranking, even with handle control set to OFF! I can easily rotate the throttle butterfly connection to closed idle with only a little spring resistance. Upon start (control at handle set to mid throttle), the engine goes to WIDE OPEN THROTTLE! Unless the governor shaft/arm turns clockwise upon start (flyweights out), and moves the throttle control butterfly closed to the idle stop, I see no way it can idle! Is my governor the assy bad? Help, I am pulling my hair out over this. Thanks for any comments! ps: I have the Choke model!
