Update: had to order a replacement carb since i botched the removal of the tamper proof red-locktited screws (grind the heads off next time lol)..
Today i received the replacement Amazon carb and this is an exact duplicate of the stock carb with the benefits including: no tamper screws, exposed a/f screw, big idle turn knob, adjustable needle (as well as now having spare carb parts). The only thing extra i needed to do was pop on a vacuum cap on an exposed inlet. Installed with 42 pilot, 125 main, needle at middle position and a/f 3 turns out and its running like a champion
Note about the carb in the link: it says PE30 but its actually a 28mm carb as required
