We all need to save this link for our children and their children.
I don't know what noise you are referring to in your video. First thing is to get a stethoscope and listen to every inch of the motor, pumps, exhaust and hear all the different noises. You may have some normal noises and some not normal. They may be melding together. It does not matter what the seller or the shipper said. What matters is how it's running for you. Noises and how it runs may be unconnected. Report an actual issue and we can help. The motor does not sound abnormal after you view the video I linked.
If it has lack of power, there is a list of checks and causes we can go over after you describe in detail what
you experience. In other words, what is the question? What is the problem?
