Has this car had a Weber carb. conversion?

[teatime39]

I'm not sure Brian , how will i know?

[Brianmoooore]

Do you have an old fashioned 'choke' knob inside the cabin, that you need to pull out for cold starting?
Also, the carb. will have a big Weber 'W' cast into it.

I have just looked through the paper work that came with car and there is a diagram of a Weber carb but no invoice for one

[teatime39]

Does this help , If you were I would you put the original BMW carb back on at the mo I'm getting around 23mpg which hurts alittle

[Brianmoooore]

If a Weber is fitted, then the spare plugs, etc. are the various connections to the over complicated electrically controlled original carb. A brilliant design when it was new, but you don't want a 25 year old one!
