Hi Grumpy/Guys

Thanks for your help!

The good news is that the engige could start now after I filled the oil, not overfilled. The problem is that it still shut down 5 ~10 minutes later, and the engine is very hot(yellow arrow side)even the red circle side is hotest. I left it cool itself about half an hour. It could start again and worked around 5 ~ 10 minutes again, then engine automatically stopped. That means the engine only could work 5 ~ 10 mins every half hour. What is wrong with the engine?
