which carb

[bsaalf]

hi all just wondering do anyone know the correct carb which would have been fitted to a 1960 super rocket and what would be the best jet's etc regards alf..

[rocket man]

its a 389 monoblock i dont know the jets sizes thoue

[Richard]

Yes
The one I have in my spares box which I took of and put a mikuni on.(sorry not for sale)
It is saying in my book a 376 with a 1 1/16th choke size, a 250 main jet, a 376/3 1/2 throttle valve, a 0.106.5 needle jet,(position 3 from top)
This should give you a good start but some jet and or needle position may be required once you start her up
I can of course look at my carb but not tonight

having read the thread that came in as I was writing I must  say that I thought it was a 389 but have just quoted from a haynes manual so if you are not in a hurry I can check my old one out some time over the week end

thanks guy's i can't make my mind up between the 376 and 389 although i think maybe the best would be a 389 maybe richard you could be so kind as to check your old one for me, i also am not sure about the other numbers after the 389 eg 037 etc what do they mean !

                 A 1960 SR would have had a 389 as would a 1960 Flash.

The Amal listings give the carb for a 1960 Super Rocket as a 389/46 (stamped on the flange), an 1 5/32" Monobloc fitted with a 420 Main Jet, 25 Pilot Jet, 106 Needle Jet and a Number 3 slide. The needle position is 2 and the lid has ferrules rather than adjusters in it.
