I bought a used HuaSheng 49cc (Dax engine) last summer. Was going to build a mount for bike attachment and give er' a try. This engine has the gear reduction box mounted to the PTO side....nice set up. Problem right off the start was the carb; previous owner let gas in the float bowl evaporate leaving a very thin film covering all inside parts of the carb. Problem with this is when this film breaks loose in the float bowl, it will quickly clog the main jet. The only thing worse is to let a carb dry out with water in it , cause you will get white rust and there is no cure I'm aware of for that problem. After trying to clean the carb in Chem-Dip, I gave up and decided to buy a new Honda card for their little engines. $50 later, I got a bright new carb, and after switching out some of the control levers, I was ready to start it up. After starting, one thing became clear, the engine would not rev up....seemed to be running out of gas like I had some clogging (main jet???). After many attempts, I ended up putting the main jet from the original carb, into the Honda unit, and now my little engine runs like gang busters
My guess is there are a few different jet sizes for these carbs/engines available. If this happens to you, don't give up
