Motor turns counter clockwise

I am wondering if any one can tell me why the engine in my AC- D-14 turns counter clockwise ?? When I bought it, the battery was hooked up Neg. Ground .. I changed it to Pos. Ground and it still turns the engine over counter clockwise. The distributor is turning clockwise. Secondly, when I bring it to TDC on the flywheel, it is TDC #4 not #1
 
#1 and #4 go up and down at the same time, check to see if #1 has compression on the way up. as for it turning backwards, is it turning cc while you're in the seat?
 
The starter can and will only engage in one direction. The bendix will only extend if it is spinning the right way.
Polarity will not reverse a starter motor.The motor should rotate clockwise in relation to you facing the front of the tractor.
If it does not you have the wrong starter in it.
 
turn the motor over 1 revolution and #1 will be on compression and #4 will be on exhaust stroke. Its a 4 stroke, every other revolution it is on compression. starter always turns the right way, dont matter what polarity or voltage.
 
No1 piston is near the radiator and when its at TDC on the compression stroke both valves should be closed and the timing marks aligned. Hal
 
I think the rotor is suppose to turn CW. Hal
PS: Stand in front of the tractor and watch which way the damper rotates when a helper makes an attempt to start the engine.
 
here is the simpliest way to tell if a starter should be cw or ccw. if the starter goes in the front of the bell housing and runs parallel withe the engine block its a cw winding starter. if it goes in the back side of the bellhousing its a ccw starter. paint one tooth of the bendix with the starter on a bench run the starter in the position it attaches to the bell housing and see if it spins the correct way.remember in a gear to gear application the drive gear turns the opposite way you want the driven gear to turn in this situation the starter should turn opposite way you want the fly wheel to turn.
