fishingrod Posted December 20, 2006 Share Posted December 20, 2006 Have you thought that it might be the throttle cables/linkages are not returning to the home (idle) position when you throttle back. Maybe something there is worn, out of adjustment, needs some grease or a spring has lost its tension? Just get a mate to move the throttle cable forwards and backwards and watch all the linkages under the cowl to make sure that are doing what they should.

Chris 55 Posted December 20, 2006 Share Posted December 20, 2006 Hustler I take it you tested the throttle unit fitted to this motor on another boat and it was working OK You have now fitted it to your boat and it won't return to idle after you have used the throttle after warm up This shows that the problem should be in the fit up of the throttle unit and cable For a fingers crossed quick hopeful fix try resetting the cable adjustment, hook up the hose and run the motor check for airleaks while your there and see if the problems fixed If the problem still exists you will have to go back to basics and go through the process of elimination as per the next part of this post To confirm this you will need to disconnect the throttle cable from the motor and check the throttle responce for free action and to see if the return spring/s are working and connected if this is OK then you should hook the hose to the motor and run it, pick up the revs after a warm up period and check the throttle return also check for any airleaks around the carbies if all checks OK go to the throttle unit make sure it works freely before reconnecting the cable to the motor If it feels sticky when worked check for any pinch marks on the cable, if its all OK then lube the cable and reconnect adjust so there is a little preload when in the idle position this should make sure it returns all the way I'll PM you my mobile number and you can call me if you need any help I'm just up the road at Bankstown so if your still in trouble I can drop by regards Chris Link to comment Share on other sites More sharing options...
