Progressive carbs have one venturi larger than the other. The engine relies on the smaller one at low/er revs, and the larger one kicks in at high/er revs.
The designation would also be a fraction, vs a single number. 32/36 are the Venturi sizes, vs say a 40IDF which has two venturis of equal (40) size.
Typical rebuild operation goes like: disassemble, clean, blow out, clean, blow out, damn where did that jet just blow off too??!! Them set float level (depending on if the float was changed), and reassemble. Seems simplistic, but if jets and orifices are clean, and gaskets seal, you are well on your way. Crud and deposits are your enemy.
On the side of the carb, there will be a cast-in number. Sometimes you can just take a piece of paper and push it up against the casting to get the numbers off it if they are obscured. They are typically on the flat between the venturis, on the acc.jet housing, or the side of the fuel bowl.
Good luck!
