[Vwdiesel] top speed issues continued or, My Rabbit is a Snail

[Forrest L King]

First, thank you for all of your replies, both on and off list.  I tried
it all!! :)

Ok, here is the update:

Airfilter is clean, even tried a run without the airfilter!!
Injectors are new
Fuel Filter is NEW.

I tried running the rabbit on a bottle of diesel from under the hood.
the problem persisted.  and Damn, these things really pump some diesel
through that pump - thank god  we have return lines!!!  I could empty a
12 oz bottle in about 1 minute 15 seconds!!

I also checked the valve train timing - the cam, injector pump, and crank
are all in time.  unfortunaetly I decided to check this after i did my
bottle runs - those little valve cover bolts are freaking HOT when you
are trying to remove them.  Got it all buttoned up.

I am now going to try and check the injector pump timing - even though I
don't see any signs that the pump has moved a BIT.  I have the adapter
and an SAE guage,   so I need to find a website with some accurate and
precise conversions of the timming measurements.

Assuming the injector is in time - because I think it is,   could this
problem be 'bad fuel' ???   I think I might drain the tank tonight,
backflush the in tank screen by pumping pressurized air from the engine
bay back to the tank.  I'll put some reputable fuel in it, Texaco fuel.
The crap I am using now was from a diamond shamrock in BFE west texas.  I
think they were surprised I actually got auto diesel instead of Farm
diesel, lol.

My friend bought a compression tester with a VW diesel adapter - it is
supposed to arrive in the mail today or tomorrow.  But I think the engine
has good compression - it starts on the very first revolution everytime.

Anybody have any more suggestions?   this is my only car right now,  I
sold my Cabriolet a few weeks after I got this running, and now I am
really regretting that.

Forrest
