Well that dia, did you use a drill for a gauge? Is that exact? From what I see that is larger than the #32 Drill listed in the Dyno Jet kit, which is .1155".
Yes a hole in the Diaphragm is bad, it will cause the slide to rise slower than the others, less fuel from the needle jet circuit, and probably a hesitation on that cylinder.
