Howdy,<br />I am a real newby. I need a small motor for my 10ft porta-boat. I am thinking about buying a 86', suzuki, 2 stroke, 4hp, short shaft motor for $400 from a dealer. I saw the original box it was stored in. The motor looks unused, with the cover off there isn't a speck of grim or dirt on the engine. The "certified" mechanic said the gas was like varnish, but he had cleaned the carb, rings, pressure tested the lower unit and changed lub, and tested the compression and got 85. I live in dry air at 6000ft. Does this sound like a deal? What would I want the guy to guarantee? Thanks for the help. Bill
