If the carburetor was properly cleaned including the teeter-totter float needle then you may just have accidentally changed the setting screws. Try setting the the high end and low end adjustment screws the standard settings are: Low speed screw: 3/4 turns out (+ or - 1/4 turn for fine tuning) high speed screw: 1 1/4 turns out (+ or - 1/4 turn for fine tuning) If the previous owner rebuilt the whole machine but could not figure out why the boat would not rev out, the next thing to do is remove the water box and and split the halves. http://www.bikebandit.com/houseofmotorcy... If a mouse nest has been built in the exhaust system the extra back pressure could be the problem. If the exhaust coupler has broken rubber tubes, has come apart, or has not been put together correctly that might also be the cause of the problem.http://www.bikebandit.com/houseofmotorcy...
