Unstable throttle of single cylinder gasoline engine?

Reasons for unstable throttle of single-cylinder gasoline engine: 1, and the phenomenon of vibration of the horizontal bar machine itself, so don't confuse it. Try to see if it is stable under the conditions of acceleration and speed. If there are no other problems, try to increase the idle speed.

2. There may be something wrong with the carburetor. Check whether the idle oil passage is blocked. If the full speed is not good, first check whether the circuit system, especially the high and low voltage circuits, leaks electricity, and then check the electrode gap and burning loss of the lower spark plug.

3. Check whether the cylinder pressure reaches the specified value. If the cylinder pressure is too low, you need to go to the repair shop for disassembly inspection.
