I picked up this carb:
Which Colvin identifies as a as a 327/275 (or 295) AT w/AIR, 3rd type. I'm assuming that this would indicate a CA emissions carb.
Any idea of when the 3rd type was phased in?
The date reads 1420 which I am interpreting as 142nd day of 1970...am I in error here?
If that date is correct then is this a service carb?
