Do You Use O Ring On Amal Flange?

Featured Replies

just been doing some research etc and just ordered a new rubber manifold flange from inmotion

as the carb face which fits to flange on inlet manifold is smooth do you use a o ring as shown in manual as there is

no cut out in flange on carb for o ring to fit in ?

or does carb just butt up against the rubber flange ?

help appreciated

i never thought id see the words: ring, amal, and flange used in the same sentance.

Hi Dave. I think the Bultaco`s don`t use an O`ring on the Amal carburettors. I know a fair few of the older British bikes use them as in Triumphs and such but I have never seen one on a Bultaco. Cheers Graham.

My early 250 and the first 325's were flange fittings had no O ring but they had 627 Amals made in Spain Other Amals 626 and 930 I used on my BSA do have O rings and are made in the UK
