      I see most Leopards running the HL334AB Tillotson, but rarely the HL334A. Is there a downside to the 334A?

      The difference between the A, AA, AB is where the machining of the carburetor was performed

      A @ IAME before 2001

      AB @ Tillotson

      AA @ IAME somewhere around 2007 IIRC

      That’s interesting. EC carbs has the HL334A as having a 19mm venturi and the HL334AB and AA as having 23mm venturi. Supposedly all have 25.4mm throttle bore. Is that info wrong?

      The venturi’s look to be the same diameter between the “A” and the “AB”. I saw that same info and measured them
