1楼, My friend has problem with about 3 years old mower. I started once and mowed a little and stopped. I could not start again. I checked air filter and engine oil. All looks OK. Next time I may check plug. What else should I check. Thanks
After checking the plug, you need to check the carburetor。 For an old machine, especially was not in use for a long time, the carburetor is very easy to be clogged. Remove the carburetor, clean it using carburetor cleaner. Pay attention to the very small hole in the center pole of the carburetor. Use a needle to make sure it is not clogged. It is the place to cause trouble for an old and unused machine.
