[Vwdiesel] Injection pump testing for beginners ----( OLD RAbbits mostly )

[H.Hagar]

I cant think of a more important issue that I can contribute to here , than this.

Thousands of smoking Rabbits out there are smoking because the timing ring is not
moving --according to internal pump pressure.    Two possibilities ---the ring is stuck
or the pump pressure in not moving timing Piston.  To say it differently   you may have a tired
pump  ---- and yes a tired pump will make her smoke and be lethargic.

This is first hand experience  ---not something I read somewhere.     

FAQ :  Can a complete newbie DIY   do a test on pump for little money , and
without removing pump ?

A :    YES.

One thing  ---please do a bit of reading in archives before you ask questions here.
Put archives on you favorites.   The internal pressure on a good pump should be
between    about 35   psi  and 100 psi. .On a tired pump it is acceptable to simply
leaving cold start knob out all the time.    On a tired pump use lots of RPM  ---
not lugging it up them hills.      And George Allison do turn fueling screw back as
Mark Shepherd suggested. Take her back till you notice lack of power. Small
moves now----very sensitive.-----NO you can not screw anything up.

Wish you could see the difference it all made to my 1982 Rabbit  ----hard to 
believe how much difference ---getting than timing (dynamic) to work made.   It smoked
and was gutless for years----- I did not know that it was not normal. All the VW diesels
I saw here in BC  ---smoked like crazy.

Hagar.
