I just put a 441 motor in my 68 Starfire and am short an AMAL carb (930)
I have fit the 928 carb I had from the 250 motor just to get it running
and timed, but am still awaiting exhaust parts so not riding it yet
I have 2 AMAL 932 carbs that are in OK shape and
was wondering what your opinions were on the idea and
any jetting suggestions?
this is mentioned in Rupert Ratio but not much detail is given
I would have to buy a 930 anyway, so if the 932 idea
fails, no bid deal
thanks in advance
Cheers
Dennis B

The B50MX used a 932, but the 928 will probably be more practical for everyday use. The smaller venturi gives better air flow at smaller throttle openings, which is where most of us ride most of the time.

According to Roy Bacon's "BSA Gold Star and Other Singles" (so take it with a grain of salt), the B25 had a 170 main jet, the various B44s had between a 200 and 240 and the B50MX had a 250. Probably start at 240 and work down.

There was a bit of minor variation over the years, but it's mostly a .106 needle jet and a 3 or 3 1/2 slide.
