The big hole ~1/4" or 6mm on the upper side of the photo goes down at an angle to the carb throat on the intake manifold side of the butterfly. So that when the throttle is closed it puts maximum manifold vacuum below the diaphragm slamming the slide down to idle position.
That is completely In-Correct!
That angled hole is only OPEN when the enricher is pulled ON. (Choked, for cold start-up.)
And the Throttle Slide still goes up and down.
Modify at "YOUR OWN RISK"!
