There are 2 styles of Carburetor Base for the Pinzgauer.
#1 - Large Idle Mixture Screws - Clearly Visible below the idle solenoid valves.
#2 - Inset Idle Mixture Screws - These are in the same location as the Large Idle Screws, however they are inset into the casting and you cannot easily see the heads.
****Please note the picture with the Large Idle Mixture Screws, is a 32 NDIX carb, and is the same as a 36 NDIX just without the solenoid valves. Mixture Screws are the same between the 2****
