Hi
I am not a Guru, but to my knowladge the 48 dellorto has 45mm throttle plates the largest venturi they will take, like the 48 webber is a 44mm ( I think) but whatever it is the venturi sizes are the same as the 48 webber (which has 48mm throttle plates) so it was called a 48, and also because it takes bigger venturis than the 45
.
You are unlikley to find a webber or dellorto Guru these days, I would buy as many books on them as you can and become your own Guru.
Best regards
Mike

Cold start emulsion tube : 7482.1
Cold start jet : 70
