Washing the cylinders comes from the mixture being TOO RICH.
If you are that rich, you may want to use a change in the main jet(smaller),
or a few steps in the air correction jet.

I found that you can find quite a selection of jets from other models of VW carbs, from 36hp right through.
So which ever way you plan to change the mixtrues, you should be able to find the jets you need from those carbs.
