Gents,
See the main issue with the carby in the top left corner of this pic. The weight on the top attaches via a brass pin to what i'm assuming is a butteryfly type valve to increase/decrease petrol volume. The problem is that the brass has come loose from the weight and therefore does not grip and turn the valve correctly. Hence why a previous owner has used what appears to be a type of bog to reattach the two.

Does anyone know whether this piece can be removed and replaced? If it is possible its not easily evident how to go about it. I also noticed Gummy that the piece in question is not shown in the diagram?

thanks,
