Baotian Comfort #4 buying a new Keihin brand carburetor CVK for GY6 engine

Episode 4 in the Baotian Comfort series. Finally decide to get a new carburetor since the others do not work well. Will be interesting to see if this solves the bog down problem. Carburetor is PD18J CVK made for GY6 or 139QMB / 139QMA engines. This is Keihin brand. Do not know if it is a clone or original but the quality is nice. It was not the cheapest carburetor. Also find that the kick assembly makes strange noise. The bushing is probably bad.
