I have had problems with Chinese engines in the past. Years ago they couldn't make a decent carb at all. But lately they seemed to do better. Still seems it is hit and miss though, so hard to say if they got it down pat yet.

About a year ago I did a little writeup and review of a couple of ASP 61 four strokes I saved from a fellow modeller's junk bin. The engines ran OK using 15% or 20% nitromethane content fuel, they did not like my regular 5% fuel at all.
Anyway, you can read about my experiences at the time with the carbs on them here in this thread. I had to mess with the carbs to get them to work.
