Default Re: 4 stroke Hau Shang engine

There is an idler jet below the idle screw. It is a plastic thing that fits into the carb.

Take out the idle screw and ease up the idle jet with a screwdriver.

Look at it and see if the o-rings are in place. Sometimes they get mashed.

If it doesn't look good, get another idle jet.
Drive fast, take chances.
