Tanaka 35cc HP Carb Kit: DOH

[thermox]

Well, it seems like immediately after I've solved one problem... another one comes up with an equal or even greater annoyance factor. I was trying to fix a slight gargle on the very top end, adjusting the high speed settings here and there, and it broke. I have about an eighth of an inch of threads left on the other part of the screw (the part that ISN'T lodged in the carb... ).

Any suggestions?
