Yes a lot depends on which carb of what size, but another major infuence is what has happened and been done to the engine in the intervening 57 years.
The supply of jets you have been offered will be invaluable for trying. Check the slide cutaway, too
Go to the AMAL/Burlen site and download the carb tuning/set-up guide - it's a PDF. It is the only way to set an AMAL.
A quicker way to get it right is to put it on a classic friendly dyno, providing the operator knows and understands that s/he MUST follow the same sequence of settings.
Beware of the morons who think their dynos only work at full throttle. The dyno place must have and use a powerful fan to blow cooling air over the engine whilst it's under test & checking key temperature points with an infrared thermometer or better is more than a good idea.
