24T2 parts for Petter A1

The needle valve is letting by and ultimately causing the engine to stall.
I bought a carburetor repair kit for a Furguson T20, which uses the 24T2, from Longford Tractors just to get the needle valve but it was a different size and thread and had to go back.
Question is, are there two types of 24T2 and does anyone know where I can get a needle valve for mine.
