original PWKs

[narx]

I've found a very good deal on genuine 28mm PWK on ebay. Carb is from 2007 KTM 105SX. Now I am confused with all those hoses, how many air vents does original PWKs have? I've seen pictures of it with only 2 air vents. In short, could I have any problems making it work?
Here are the pics:

no big deal, it doesn't matter if it has 3 or more vent tubes, it will not affect performance. as long as the carb internals are in good condition it will work as it should.

make sure all those tubes are not blocked from dirt.
