Charlie,
You are correct Apart from the MG2, MG5 and some MG6 there were a number of mowers and the Ransomes overgreen fitted with versions of the 244 and model 15 Amal carburettors which all use the same float.
I really need to consider the demand carefully as based on the minimum order and tooling costs the financial outlay is considerable. I have also just committed to tooling for a batch of fuel pump glass bowls for the MG5 and MG6 engines. (I still have glass bowls for the MG2 Autoklean filter)
As and when I get anything I will put them for sale in the cultivator.
One day I will retire !!!
