[Vwdiesel] Rabbit droppings # 46 -- ( How to get lots of mileage )

[H.Hagar]

Doug Ferguson :   Sounds like a "Hillbilly Tuning"  job is in your future. 
and I am specific there.       " Astronomical mileage ? "  I shall test with a bottle
of exactly measured fuel.
The stroke on these wonders are fixed at about  80 thou . And you are right
about fuel in ,  is where the GO power comes from. So the timing of pump
is your next step. If that does not do it  ---check internal pump pressure versus
RPM.     at 1000 RPM (pump)  the pressure should be  4.6  to  5.2 bar.
That's you timing advance.

I would move the pump a pencil line advancing and park next to a known good one,
and compare sound.    Pumps usually need to be advanced more than books say
on older VW diesels.
