I've had 2 of them and they've been inconsistent. The first one had great power but stalled all the time, which turned out to be a simple problem. The second doesn't have near the power of the first and takes half a dozen pulls to start, the first one started first pull every time. They both bog then take off when applying the throttle. Chinese manufacturing tolerences just suck. You may get a good one or you may not.
I like my Robin/Subaru EHO35 a lot better, even though it doesn't have the power of the Huasheng. The R/S is very consistent on starting/running and there's no bog when applying the throttle.
