1989 BMW 323 mileage: 162,000. I have had trouble starting my car from a cold start, it has an automatic choke but I have had to put my foot on the accelerator to get the fuel to carburetor until the choke takes hold at about 20000 revs. Then when the car engine is hot and the engine idles at about 9000 I have no trouble at all, I can start it straight away. It doesn't stall or anything - I had the mixture done by a BMW mechanic but so far, he can't suggest what may be the problem, any suggestions?

It is fuel injected. If so, the thermo time switch for the cold start injector may be faulty or it may be the coolant temperature sensor.
