[Vwdiesel] Rebuilt IP / Engine Won't Start

[William Longyard]

Bill,

The truck ran find until I changed the pump.  I changed the pump because the 
seals in the old one were leaking.

When I adjusted the fuel screw both in, and out, there was NO difference in 
the amount of smoke produced, only the engine speed changed.

The idle screw has to be adjusted all the way out to get the engine to idle.

If I take out the washer that goes in front of the fuel screw, and thus 
screw it in another 1/8", the engine speeds up, doesn't smoke, and I can 
also get a little play with the throttle, though opening the throttle causes 
the engine to slow down.

I believe something is wrong with the throttle, but am not sure why just 
barely touching it (with the fuel screw set normally) would cause the engine 
to stall.
