Lude Generation

I'm panning to fit a 62 mm throttle body off a ATR
BUT when I've looked at mine it has what looks to be a cold start on the bottom ???
Does anybody know what the ATR uses or is it even anything to do with the choke???

Look here:

P.S. if it will be your sumemr weekend joy car - don't bother, you don't need FICV.
