Turn the choke ON to start a cold engine. Once it is running, set it to PARTIAL until the engine is warm. Once the engine has been running a few minutes, set the choke to OFF.

Choke helps the engine run rich. This is necessary when the engine is cold. The engine will start easiest with the choke on. The engine will run best when warm with the choke off.


I believe you have a carburetor engine, and you need to adjust your idle, make a richer air/fuel mix. Your Idle mix is too lean, so you can't start it. When you get it richer, you might need to adjust a throttle.

If you have only 1 screw on a carburetor, it'll be a throttle adjustment for idle. Try to start it warm with opened choke and a bit of a increased throttle (1/4 - 1/2 of a handle). If it starts, just turn that one screw in a little. If it starts okay after this, but idles at too high revs, you'll have to go back to lower idle and get used to start with opened throttle.. Unfortunately cheap carbs don't have the best adjustment options...
