The fuel tap on the B is gravity fed. Are you saying there are no vac pipes from the top of the carbs?
There are clocks about for the CSR but you are looking abroad. New ones go around £65 each plus postage etc. Second hand ones are a guess. The ones I have are tatty but depending on your skills can be refurbished.
There are/were 2 CSR’s on ebay and a CSR engine badly advertised as a B engine but no I didn’t get any.
Good luck at Kempton on Saturday.
