[Vwdiesel] Hillbilly tuning --- ( the cold start knob ).

PS : If pulling knob makes NO difference when idling ?  ---you likely have a
GOOD pump.


  When cold, the knob should make QUITE a diffference. When warm it 
should make a slight, almost barely imperceptable difference in the 
sharpness of the knock.  That's the way I use to check if the timing's 
correct.  If it makes NO difference then the timing is usually retarded.
This is on nearly NEW cars so it's unlikely they were all "bad."
