Bought new about 2 years ago for $650. Top quality USA made. Has 1 1/8" keyed shaft so could be used with belts or Lovejoy "J" coupler. Weighs about 95-100# so shipping is a problem. Never used the generator and don't have an engine for it anymore. All specs are listed on the Winco site under "2 bearing" generator. First $150 cash gets the prize.
