the biggest issue IMO with the clones is lack of QC, so some might flow enough, others not. I have found on some that the fuel passages are srilled too small or worse theyre misaligned. so like there's a 3mm passagewat drilled from the spigot and a 3mm passageway drilled from the float bowl, but they're off center and only align like mayb 1mm^2 actually, and your flow sucks and it drains. I've seen that on a phbg clone, a SHA clone and an OKO clone (which is aleady a clone of the PWK, but the real OKO's are decent, the clone of a clone tho? anyone remember the movie duplicity?)
what's wrong with your dos gauge? I've got one and its been great. some folks have mentioned issues related to RF or something?
