Hi Packy,
Austin Healey Sprite MkIII 1098 1964-66 AUD136
MkiV1275 1967-68 AUD136
Standard needles are AN with Blue springs
Also supplied to the MG Midgets, same years with same same
Austin Healy Sprite MkIV 1275 1968 AUD266
MG Midget MkIII 1275 1968 AUD266
Standard needles are AN with Blue springs
All are HS2 carbs
The AUD266 seems to be a USA specification. Do't know what the diference
in the carb bodies are, but the needles and springs are the same.
All the above information from the Haynes SU Carb book.
