Amal concentric and 16m

Hi - I am thinking of putting a new concentric on my 1947 16m - the current 276 is playing up and no end of fettling is making it tick over so it looks like body wear.
I am thinking about going concentric if something else - any advice and jetting required would be appreciated.
Thanks I advance

I'd dump the idea of a concentric and get a monobloc. You'll be forever mucking about with the concentric.
Sorry, pre-mono 76D/1J

Hi Angelo,
Hope you are well, long time no see, if you speak to Amal they could advise you on what size and set up to use.
Kind regards Colin

This would of course cost a lot less!

I put a new concentric on my 1953 M16 , to re place a very worn Carb . Been on now over 2 years with no problems at all . Tickover is smooth , starts first kick ( when there's no public audience ) . Fuel consumption improved

I wonder if you had the spec for the concentric - size and jets?
Thanks
