Title: B31 Carburettor
Post by: gmann1340 on 11 September, 2017, 18:25:43
Hi
Could anyone tell me which 376 carb I need for my 1953 B31 and has anyone got one to sell? Thanks. ( I know it should have a 276 )

Hi all,
I am thinking of fitting a concentric to my B31 to replace the 276 which is now cream crackered, I was thinking about the Amal 626.
Any thoughts?

Cheers
Chris

Chris.
Ive just taken a virtually new concentric off my Ariel 350. Whilst the bike ran perfectly with it, I have now put a new Amal monobloc back on it - the bike had been restored by a previous owner and kept as a showroom ornament for years  :-\ If youd like me to send you some pics of the carb and more details let me have your email address via a pm.

The 376/2 was used for 1955/56.

As JulianS said, the folk at AMAL are extremely helpful and would probably advise you best. Be quick though - they've got only 2 left  ;)
