Sorry, no idea where to get from a chinese source. Anyway it's that infamous https://en.wikipedia.org/wiki/Chunyun again, it will delays ur project even can find 1.
HB, do you know where I can buy a front motor mount for my j2005 Jailing GY200 that would have room for the counter balance shaft in front of motor? My old motor was a JL163FML that did not have a counter balance shaft so the old motor mount doesn't fit. The new motor mounting bolt holes are farther apart with the lowest bolt hole in motor being the different one from original motor. top 3 mount holes are in same place as original, just lowest hole on bottom of motor is maybe 1/2" farther down.
Also the new motor's mounting hole casting is wider from center of engine case to the RH clutch side of motor . I think the RH side of the motor mounts on alternator side are same as old motor. Thanks, Rj in Walla Walla, usa
