Had SUV back to dealer a couple of times for foul odor from exhaust , and lack of power. After adjusting carb on one of the visits to dealer , it started back firing more loss of power and still having foul odors from exhaust. When I dropped gator off at dealer last week told him ,gator would scream every time you asked him to go up a hill. Still having trouble getting it started, still having lack of power and would still backfire going downhills and at times going from a dead start. ToCalled dealer today since I hadn't heard anything. Seems the supplier for B&S that makes their head gaskets was using defective material So one head tested ok for no leakage. The other had loss after engine was hot tested OK when engine was cold.
Dealer is waiting for new head gaskets from B&S.
