I Finally did it yesterday!
thanks to all that reply to my post
But that side plate its a little difficult to remove
if you not remove the intake manifold, so I made a
research
that allen head (4mm) rotates with the main shaft of
the injection pump... so to find it you have to rotate
the engine, I use the 9/16 bolt of the hydraulic
direction pump, so what I investigate is that this
4mm head can be adjusted removing the upper cap only,
you will have to remove the upper cap and some kind of
shaft that has springs outside by removing the center
shaft of it that has also an allen head, below this
shaft with springs there is an small hole, inside are
the same 4mm allen

turn it clock wise it will give more fuel
I turn mine about 90° counterclockwise!
smoke reduces by 60-70% also advance the timing like a
1/2 °
noise change! before it appears like I have a
non-working piston
now the angine can handle a rapid acceleration and
desaccelertion without shut itself off
and what a beautifull sound...
now it even starts at the turn key!
with this behavior
  who are worried about that little smoke?
