Just found this site. Boy, am I glad I did!! I have a bike Zongxi (or something like that) with a 150cc Lifan engine. I looks sort of like an old Honda XR185. It's basically a decent bike, but I need to find a thread that addresses carb issues. Mine has had a 'flat spot' at low rpm since I bought it. I keep the bike at my dad's place in AZ and ride it in the winter.

Thanks for being here!!

Hi Rev_Rock

Welcome to ChinaRiders!!!

Most cable activated carburetors have a so called flat spot... you can't just slam-twist the throttle the engine will not accept the fuel & air mixture that fast. These are not CV carburetors that accept fuel/air 100% better.

Try backing out the low speed mix screw a bit.
