Older Winco generator that runs at 1800 rpm instead of 3600 rpm. Produces 2000 watts. It does smoke at startup but clears up completely in about 3 minutes. This unit is heavy because of the double windings necessary to run at the slower rpm. I suspect the copper in the generator is worth more than the asking price. The older B&S engine block is solid cast iron. This has been a useful generator during power outages. Still starts and runs like always.
