Hi everybody, the 1951 C11 I am working on came without a few parts namely the bin that held bolts and random small parts. Made all missing parts except for the carb float seat and the few parts shown that attach to the bottom of the float bowl as noted in the attached picture, if you have an example would you be so kind as to take a picture and some measurements especially the needle seat would be greatly appreciated and I can machine them on my metal lathe. regards, John

John, if you just want a reliable runner get a new Monobloc set up for the C11G. At least it will buy you some time to work on (or source) an original carb. Just a thought from an old sod who values time.

Hi John
This ebay seller looks to have all the bits you need  for small bucks ?
a  float chamber for £15 ?
I have never removed the float needle jet  ::)

This is on my 53 c11.
You can get the solder nipples and nuts on eBay.  They were 1/4" - 1/4" pipe
