[Vwdiesel] 82 Rabbit diesel - injector pump lever is "sticky"

Hmm... Interesting point, as I did "gunk" the engine about a month ago as it
does have a minor oil leak.  Haven't found the leak yet, but it seems like
it's on the timing belt side of the engine.  (was throwing a bit of oil onto
the inside of the hood as the timing belt cover has been left off)  Engine
allegedly has 20K miles on a rebuild, though I'm starting to question
exactly what was "rebuilt".  I'll work the springs/lever with some WD-40 and
report back after I've tested it for a couple of days.

 It's actually ok.  The way you set the max rpm is:  warmed 
engine, in neutral, brake set, pull throttle to max, check rpm, 
adjust as needed.

  Try some WD-40 on the throttle shaft, lever, springs, where they 
all meet.  Spray it good, work it a couple times and see if that 
doesn't do the trick.  There's a lot of tension on those springs so 
if the cable is adjusted to allow full return, it's unlikely that IT will 
restrict returning to idle.  It's usually in the springs/shaft area.  A 
little lube should fix/help it.
