I would find out who actually manufactures the generator as I believe Westinghouse is no longer anything but a name. A few years back one of my neighbors bought a Stanley branded generator that was not manufactured by Stanley, but by some company that merely paid a licensing fee to Stanley.
The actual manufacturer was a Chinese concern, and the US operation that imported them, marketed them, and allegedly supported the generators provided horrible technical and parts support to not only the end users but also to those repair facilities in their service network. Unfortunately, my neighbor did have a bunch of problems from the get go and was finally able to get his money refunded by the warehouse club he purchased it from.
Do a little online research first to find out who makes the engine, parts availability, service network, etc., just in case you have any problems.
As and aside, I purchased a Coleman Powermate Generator with a Briggs and Stratton engine from Home Depot about 20 years ago, and within one year the engine would not turn over when I pulled the starter rope. Home Depot referred me to a repair shop about 1 mile from my house that was in the Coleman Powemate repair network, took it over, and three days later I picked up the repaired generator and have never had another major problem since. Also, parts for the B&S engine are readily available should I have a problem in the future.
Good luck!
