A50 Carb
« on: 04 March, 2017, 15:16:13 »
 :)Greetings all.

What carb should I have on my 1963 A50. Currently have a monobloc fitted. One book says monobloc and another says 626/19 concentric.
Still on the bench with another few months(years?????????) to go, so no rush to change it if its wrong.

So any input very welcome.

Thanks a zillion.

Mike ??? ???

Mike

The concentric came out in 1966 and BSA fitted them to some 1967 season bikes such as C25 and A65 Spitfire Mark 3. The A50 got one for the 1968 season.


Your 1963 A50 would have been fitted with a 1 inch bore monobloc 376/382 according to ther 1962-64 Amal settings list. With 250 main jet 3 1/2 slide needle in position 3, 106 needle jet and 25 pilot. It would also have had the interesting tickler arrangement due to the carb being shrouded by the side panel.

It is not unusual to find concentrics fitted in place of monoblocs.

Hi agen.

Thanks for that. I've actually been looking for a "tickler" set up, but they appear to be rarer than hens teeth. So I guess I'll have to make one.

I've actually got the monobloc as described by you.
