I built a block off plate, for mine.
The screw idea sounds, good, i did not know that hole was threaded.
I checked mine for vacuum leaks when i got it started, a couple of times,
on all parts of the new system and also this vacuum port area,
by spraying starting fluid at every part including new Hose connections, base of carb, to see if there was any engine RPM speed up or slow down in engine RPM's.
There are no leaks.
But Knowledge is good, since this carb is on my bike, And I like it.
I would like to know as much as possible, about it, it may help me some day.
