Why do you want to buy it, something wrong with yours? Personally, as a service tech, I wouldn’t buy anything like that because I have no way to know if it is any good. Those assemblies are easily ruined when carb cleaner comein contact with them.
IF that is the Cobra made by Global Garden Products in the EU with a genuine Honda engine then it is a good unit
If it is the knock off made by World Lawn in China with the pretend Honda engine ( H.Onda ) then it is junk
