i gave it another shot of carb cleaner just now. im gonna let it soak for about an hour then resoak it and spray the crap out with a can of compressed air i have. the allen screw on the outside is completely stripped and i cannot adjust it further. im going to try some creative methods to tighten/loosen it.

the one i swapped in earlier this evening adjusted just fine, so i know somethings up with mine.
