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.
