  If your Hyundai chainsaw engine won't start, it could be due to several reasons. First, there might be water in the fuel or a substandard fuel mixture; in this case, replace the fuel. Another possibility is engine flooding, which requires removing and drying the spark plug and then attempting to start the engine without using the choke. Lastly, a missing or weak spark could be the issue, indicating that you should replace the spark plug.

  If your Hyundai chainsaw lacks power, accelerates poorly, or idles roughly, several factors could be responsible. It might be due to water in the fuel or a substandard fuel mixture, requiring you to replace the fuel. The air filter or fuel filter could also be clogged, so cleaning or replacing them is advised. Lastly, a badly adjusted carburetor can cause these issues, necessitating an adjustment of the speed needles.
