I recently had some work done on my Cyma CM048m's gearbox(v3), and I noticed a slight issue after reassembly: The selector switch is very loose when on the semi-automatic setting, even after tightening the main screw. It even seems to move upward slightly in the direction the automatic setting. At first I thought the issue was that the selector gears were misaligned, but they seem to be in working order, except for a small amount of play. The gun performs otherwise fine, but this is a rather annoying problem. Any help would be greatly appreciated.
EDIT: Also, there seems to be another problem, but I'm not sure if one is the byproduct of the other. When set to semi-auto from automatic, it stays in automatic until I pull the selector switch slightly lower than usual, then it goes into semi. Once again, the selector gears are aligned just fine, but with the rear gear having a slight amount of play when set to semi.
