Norman t300 new project

hi all just signed in as new member, I have just started to refurb a 1942 norman t300. Have just rebuild the bth mc2 magneto. I am stuck with the thread sizes and the linkage from the carb to the rear of engine where the crank handle is. would like some info on the thread size and linkage from carb. many thanks. Could any one help me with this problem because i can not go any further. Many thanks for your patients
                                   

The majority of threads will be BSF, but some threads are metric (like the carb banjo fitting, and float bolts).

many thanks. blue cat
