Can anyone tell me where I can get a new auto choke unit for this car, or a complete new carburettor with auto choke attached. I've been told by my local garage I need a new choke but normal garage suppliers don't have parts this old. Car always starts but tends to chug a bit immediately afterwards, and has stalled occasionally. Once hot it runs like a dream. Although any possible contacts would be appreciated, those closer to Milton Keynes would be best.
