[Vwdiesel] More Quantum Questions?

[mark shepherd]

Yes try tilting pump top a little towards the engine for advance, then try 
the other way.

A little squirt may happen just after stopping, if you release the fuel 
lines. However, I've just been reading and early book, that apparently the 
four fuel cut off valves , dont just shut off, but also sink back into 
themselves a bit and so reduce residual pressure in the lines and so speed 
up injector fuel cut off between injections. Bosch may have changed their 
minds about that though....

If lumpiness won't go away when running even with timing alteration, then 
try releasing fuel line for each injector in turn, until one line 
[hopefully] has no effect. Hold a rag to the injector as you are doing that 
to prevent spray hitting you.
