My 2.0L throttle body has a small hole in the flapper thing(the thing that opens and closes inside the throttle body) and my 1.7L throttle body does not have this hole.
Is this normal?

Yes...

Some people drill that hole.

Adds a small amount of idle air and keep the plenum from going to extremely high vacuum on rapid closure of the butterfly and thereby sucking a shitload of oil from the breather.









Pretty good answer...Huh?

Yes, now thats an answer.

Yuppers... Most TB's I've seen have them. I think on some Solex carbs for T1 motors, a trick is to plug that up? I guess the hole is big enough to cause a lean running condition. I never figured that out. Just gave the old Pict-34 the float test and put on something different.
