Having a problem sourcing a Dell'orto PHBH BS 30mm, seem to be only turning up with PHBH BS 30mm 4T

Q: Are these four stroke the same carb as a two stroke, only jetted differently - or - is there something 'special' going on in these four stroke carbs?

They are the same carb body casting but have some different sized air passages. Atomiser and atomiser bushing need to be changed. 4T carbs can be drilled out and made into 2T but you'll need one to compare with.
