recommended BOSCH fuel pump for XUD7TE
#25
So, I have finally rode in to the wild with my BX. I used 1.9d full load and intermediate load governor springs on stock gov. They are stiffer than XUD7TE ones and slightly rise max RPM. Idle spring is different so I kept XUD7TE. Used 1.9TD camplate and 9mm plunger instead of 8mm original.

Now it comes to setting timing. I tried setting 0,66 mm as per XUD7TE manual, but result was so retarded that I had lots of white smoke and rough idle. Because there is no access to measure static timing when everything is assembled I simply advanced the pump a few degrees on a running engine, but now have no idea how my timing looks like. At least smoke is gone, engine runs smoothly.
Is there a recommended dynamic timing value that I could set using strobe light? Pump is hybrid so I don't think I can use anything from manuals not to mention access issue.

Edit: I have found 12,5+-1 degrees at idle for Bosch fueled D8B engine (XUD9TF). Can I use this or should aim for something else?
