Re: throttle cable adjusting?
It's hidden in the remote control section Dawgs.
Push the fast idle lever down.
Shift controller into forward.
Shift the controller back to halfway between forward & neutral.
Move the engine throttle lever tightly against the idle stop screw.
Pull on throttle cable to remove backlash & install trunnion nut in pocket.
If cable is too lose idle speed might be high and inconsistent.
If cable is too tight control effort might be high through shifting range.
Does that sound familiar?
