CARB JET HS2/4 SU (L/H)

Every mini with a single HS2 (1.25") carb had this jet fitted. Also used as a LH jet on twin setups. Denoted by its black plastic base. Twin HS2 and HS4 carbs used the same bore but different lengths and angle on one side. For twins see AUD9141A/2A 30 degree float angle as per Mini fitment.
