I take it you have already found the website http://www.heckflosse.nl/ , which will give some insight into these lovely old cars. I can only give you general guidance on the problems, since I don't have one of these models myself.

The brake booster (servo) should be looked at (ie replaced or overhauled) because the hissing, is a vacuum leak which will go into the inlet manifold and weaken the mixture. Ironically, it sounds like your mixture is too rich, though. Maybe someone has over-compensated for this in the past? Its leak, will cause running issues because with higher inlet manifold vacuum (eg at idle), a greater proportion of air will be drawn in and thus, your car will be running rich or lean at different times.

Its probably not worth trying to solve the other running issues, until you are confident there are no more vacuum leaks into the inlet manifold.

air leak

i though the servo on this model runs on the back of the air pump it on it only hisses when brakes are applied does any one know how to adjust the mixture on it
