starts and revs up in neutral. kinda hard starting. has a miss in it. smokes alot when u start it and rev it up but doesnt smoke while cruising. but take off on the water and has no power but runs around 1000rpm steady, at full throttle. sounds healthy just seems like the throttle aint opened up. has new plugs, fuel pump, filter, and compression is 110-125 on all cylinders. appreciate the help!!! thanks Aaron

mine did the exact same thing... turned out to be water in gas for mine. have no idea how it got there but drained tank and refilled,no problems since. unhook line between bulb and motor and pump some gas into a clear bottle. the water will settle to bottom,kinda milky lookin if you have any.
