No problem. I'll talk to Jo and Piet and get the following translated.
The fitting instructions for the McNeilly Mixture Control Block is below and will be translated. I'll talk with Tom tomorrow to check on avaliablity.
Note: Contrary to what I said, your jets are replaced, and in most instances, the upward postion gives you the 150% of stock jetting enrichment required for cold starting, which should be about 9:1 air fuel, or 14% CO, then it gets adjusted down via an exhast gas analyser to down to get 12.5:1 or about 6% CO under load. The choked setting is in the upward position, while a position equal to about 12.5:1 to 13.5:1 (6 to 3%CO ) air fuel under load will be the normal position. The power valve can remain for a landbased installation.

Detailed instructions are included - very detailed.
1. Remove the float bowl and jet plate.
2. Remove the jets and power valve from the jet plate. The jets
are not
used as the mixture control replaces them. The power valve is plugged
with a plug available from your Holley dealer.
3. Clean the parts and trail assemble. The locator pins are
specific to each type of carb. Trial fit without gaskets in place. If the unit does
not fit properly you probably have the wrong unit - Tom will exchange at
no cost. Work down any high spots that may cause "rocking".
4. Assemble the float bowl, gasket, mixture control, gasket, jet
plate,gasket and throttle body using the new screws supplied. The gasket
between the float bowel and the mixture has to be modiied slightly by
removing the little tab on the botton of the gasket (fuel inlet). Check
to insure the accelerator pump opening in the gasket is lined up with
the mixture plate.
5. Remove the stock accelerator pump arm and install the new longer
arm.
6. Fabricate a mixture control push-pull control. Full lean is
with the
tick mark on the control arm pointing towards the float bowl. Full rich
is with the tick mark pointing normal (90 degrees) to the float boal -
either direction. The arm has to be able to rotate 90 degrees in either
direction. Tom reports a couple of users had to extend the mixture arm
to decrease sensitivity of the unit. Full rich and lean stops must be
built into the control.
7. Initial start-up will probably result in the flow being about 150%
of the stock jets. Tom highly recommends a EGT be utilized to adjust.
