Default Re: 4 stroke huasheng bicycle engine loss of power

You should check the fuel flow from the gas line before it hits the carb. Pull it off and look for a steady stream. You could also check the gas cap vent.
The spark wire connector in the boot might be bent up or not contacting the plug like it should. Could be bad gas. Could be a spark plug gap too wide.
That's all I can think of that are easy fixes.
Hope you get it running better.
Is your overall gearing (rear sprocket) from a kit? Maybe it's too tall or something.
