Just rebuilt my starter ant it seems to be turning the crank but have no compression is it possible that it is turning the wrong way

 

[Here 2 help]

There is a lot of posibilities, but turning the crank the wrong way is usually only possible if the polarity of the battery is backwards.

Take the spark plug out and see if the piston is moving up and down when you hit the starter.

Without any other info, I'm going to guess the starter clutch is bad and the crank isn't turning.
