could be the o-rings between the carb joints and the head. 

could be leaky/cracked old carb joints

try spraying some WD 40 around the carb joints while engine is running to see if idle changes.

could be as simple as sticking throttle cables

happy hunting!  :good2:

KOokaloo!

You are doing just fine ! I am sure if I was to ask a question in German you would scratch you head or chuckle. Are you making any progress in finding your problem?

Hey, sorry for complaining. 
I didn't realize you were German.  I just thought you were a lazy typer.

Give it your best shot, and I'll be more patient.

A few clues.  If the idle speed is increasing, then air is getting into the system somewhere or a throttle cable is binding.
Follow Frank's suggestions to find an air leak.  Also, make sure the choke mechanism is allowing the choke plungers to seat fully.
