Am currently trying to refurbish the MAF15B1 but cannot find internal specs for the carb as fitted, eg jet sizes, float weight etc, Can anyone help please?
Not much info seems to be available on older dellorto carbs, I would expect there to be only one float option available, quite possibly the same thing for jets.
The owners manual does include some basic information, available from here if you don’t have one. Page 35

The parts book just lists it a carburettor, no sub components listed

You could look on the Eurocarb website, they will probably have an exploded diagram and a surprising stock of spare parts.
