Cold start only without Choke, dies with Choke immediately.

Moin together. I’ve had a problem with my little, well, always. From the very beginning, she jumps very badly, when the engine is cold, and with Choke already not at all… if she then approaches, then she dumps with hardly perceptible rotary zalula (so 800 ca) before her, then she likes to die off, if I don’t react fast enough with the gas tap. If I now move the Choke even a few millimeters, she dies immediately, but then can be without Choke u If the engine then has a little temperature, so after about 1min. it keeps the idling quite stable and rises In the speed slowly direction 950-1000 revolutions, which then sounds like a healthy and round idling. If I put the choke in before I start, then the whole doesn’t sound so healthy either. The sound is not quite easy to describe, but is best to compare with a very dull knocking that par If the little warm is everything is tutti, only to get it until then is quite difficult. Warm start without a choke and without gas in 2 seconds. Well then also the real question: How would you go about this thing, how does a meaningful order of work look here? Have basically a plan of cars, but with engines with carburettors my experience value is practically not available… Thanks in advance for your help
