Try to get a hold of James Condon "generator repair man" on the internet.
Is there a product ID tag on the chassis of this thing? Black and Decker was just a sales name back then. Likely this is an early GENTEK which B&S purchased years ago.
At 3,750 watts, it is big enough to run a refrigerator, a small space heater and few lightbulbs as needed. Not made for a whole house or any well pump, HVAC or heating grid system.
This size is great for remote site operation of saws and lighting, but not much more.
