Douglas-47

I have a technical question. Have a Mki-47. The question is, what thread it onto the studs to the carburetors sitting on the cylinder and thread the fuel valve in the tank.

Hi Hakan,
                The thread on the carburettor studs is 1/4" BSF (British Standard Fine) and the thread in the petrol tank for the fuel tap is 1/4 BSP (British Standard Pipe)- yes, I know it is a lot larger than 1/4" - this is the size of the thread on the outside of a steel pipe with a nominal 1/4" bore.

    Regards,
                  Eddie.
