I have the Powerhouse PH2100PRi. It generates, if the engine starts. Eventually mine got very hard to start after a year. I dug into it myself, and the carburetor had what looked like particles of aluminum in the float bowl and in the emulsion tube, almost like stuff left over from when it was machined. Go figure, it has a fuel filter to keep stuff from getting into the carburetor, but does nothing for what's already there. The cheap paper gaskets tore when I unbolted the carburetor. Once I made new gaskets and cleaned the crud out of it, it's working much better now.
