Also make sure you don't have any leaks in the plenum and that your throttle body flap is closing all the way. After some decades it can use a good clean.

With the idle adjustment screw fully in your engine isn't supposed to run as there's not enough air to get even to 500rpm

I've already adjusted the TPS.
I have no leaks.
I've putted my finger on this big hole (marked in blue) and the idle drop down and the part (marked in black) has been like blowed.
