First check to see it you hooked the battery up backwards. The start circuitry will still work with a backwards battery - but the starter will turn backwards.
You have a one way "sprag clutch" (google that) between the starter motor and the engine (it is called a starter clutch on quads, but the generic name is sprag clutch). It allows the engine to overrun the starter motor when it starts up, and allow the engine to run and go with the starter stopped. But when the engine is stopped and the starter turns, it locks up and turns the engine.
If you hook the battery up backwards the sprag clutch works in reverse too. The starter will spin and spin - but not lock up and turn the engine(or the flywheel since it is attached to the engine).
It is also possible that the starter clutch is bad or misassembled. Did you take any of this apart?

If you battery is wired the correct way around, and your starter still spins while the engine doesn't, then the starter clutch is slipping.
