Drill the CV slide?

Guild,
Drilling the hole bigger actually an air bleed that lets the air out of the area above the diaphragm. What opens the slide is the air that flows through the oval opening at the top of the front of the carb just above the throttle bore. Try it if you don't believe me. Take and blow into the oval opening and watch the slide open.

The purpose of the oval opening is to allow for air intake by and around the enricher valve. It is in the lower chamber between the diaphragm and slide and is sealed off from the vacuum/spring side. If the enricher valve is properly seated, air blown into that oval opening will only go out between the slide and carb body.
But true, when blowing into the oval opening the slide will raise. That's because it's going UNDER the diaphragm and pushing it up.
