I have a recurring problem with the throttle on my 84GL.  I have been
working around it for a long time now and wanted to see if I could solve
the problem once and for all.  The throttle has a spring wrapped around
the top and has two levers sticking out with cams on the other side.
One cam hits the limit switch.  It appears that the other lever and cam
do nothing except hold the other end of the coiled spring.  The problem
is that the throttle starts becoming very resistive and the problem
seems to be between the coiled spring and the piece of metal in the
center of the coiled spring.  I have tried various forms of lube to see
if I could free up the throttle and the best affect seems to be graphite
oil or graphite powder down on the inside of the coiled spring.  It
seems that something is rubbing and for the life of me I don't know
what.  I have looked down inside and sprayed with cleaner and gotten all
dirt and anything else out of the spring.  It stays working for about 2
weeks (about 1500 miles of travel) and then starts to get sticky again.
It is not a problem in the pivot of the actual throttle shaft but seems
to be related to this spring.  Does anyone have any insight on this
problem?
