I drove a 1982 1.6L NA Rabbit from         25 Dec 1997  to  17 June 2003   =
smoking like stack and gutless.

Please read my thread  "My Rabbit smokes no more ,no more etc. -." (17 june=
 2003.)   The joy of accomplishment is considerable.  Nothing to buy or sen=
d out for repairs.    I asked the grand wizards to explain why  just adding=
 ESSO AD-100 to fuel would make that much of a difference. Before they answ=
ered I found the reason. It was  non functioning timing system inside pump.=
 My favorite way to solve problems is Boolean logic.So now newbies can do i=
t in short order simply by following the same procedure.
Somewhere I mentioned that the procedure assumes that you checked Valves,in=
jectors, and did all the other checks. But it still smokes and lack power. =
 The basic idea has to do with the internals of the pumps.Just like compres=
sion slowly decreases over time so does some of the functions of the pumps.=
So to compensate we tune for end results  i.e.  performance ,rather than to=
 absolute settings. There are many things we can adjust on the pump accordi=
ng to how badly worn the individual pump is.  For example , we can lower th=
e cracking pressure on the injectors. We can increase the flow from the reg=
ulator valve , we can reduce the spring pressure on the timing piston.     =
                                  Hagar.
