For some while I have had on the shelf a carb made by NFS Carburettors of
Willesden which has an odd automatic air valve and fuel needle arrangement.
It carries a string of patent numbers, including a US one 1510028, which I
popped into the google patent serch mentioned in an earlier post. Thre it
was large as life and the patentee? One Frank Hadfield Arnott of Willesden -
could it be the same Mr Arnott of blower fame?
