Sounds to me like its idling on choke fine then when the choke switches off its not idling quite high enough and is stalling. I had the same problem and found the best way to sort it is to look under the inlet plenum for a flat head screw (it\'s on the right from memory) screw this all the way in then adjust the idler screw (where the throttle cable is) you can then scre the inlet plenum one out a bit again until you find the perfect balance
