This is a M102.980 engine, but the K-jetronic is basically the same as with the M110.
Two subsystems control the mixture in warm-up phase:
[*]The warm-up regulator ('Warmloopregelaar') does enrich the mixture by lowering the control pressure. Inside the regulator is a bimetallic spring that could be broken. You can check the warm-up regulator by measuring the pressure at both connected fuel lines in warm-up phase. If you don't have the equipment, disconnect the fuel lines and try to blow air in. If the regulator is working basically the air should come out of the other connector
[*]Secondly look at the auxiliary air valve. In warm-up phase this valve is open for extra air in order to rise the rpm. See the picture, part no.3. Again this is the situation in a M102.980, but for the idea it should do
Inside there is also a bimetallic spring that could be broken, or airflow to the air valve could be blocked

The engine starts immediatly on cold start, but the cold start idling speed is too low ( 550-600 rpm) and the engine stalls. It used to be about 850. How can this be adjusted, or does something need to be cleaned/changed. Once warm, the engine runs at around 700 rpm on idle.
Chassis number is WDB1230531A256819. Thank you in advance.
Engelse Hans.
