Please Adjust it with a Clock
D24T is VERY sensitive about wrong Pump Timing. !
Good Tutorial:

But time it on the Camshaft sprocket (Loose screw only 1 Revolution !)
Its easier !.
But note, on a Standard Clock (Every clock offered in ebay), the Pin , which is installed in the guide in the Pump (Where the clock is mounted on) is to Long - You cant mount the clock correctly)!. I had just shortened it about 10mm.
Setting (For Europe) 0,90mm
