Okay guys, I need some help.
This is driving me crazy.
I took the deck off of my Troy-Bilt Pony to change out both blade pulleys.
While I had the deck off I changed the upper and lower belts.
I tried to crank the mower to see how it ran with the new belts.
Well, I couldn't get it to start up.
I could turn the top with my hand but it stops when I try to go clockwise.
Starter is good.
So I changed out the carburetor and the solenoid back by the battery apartment. Oh and a new battery.
I just don't know what's wrong with it.
Thanks in advance

Check the valve clearance. While you are at it check the compression release. Turn the engine over and watch the bottom rocker to see if it bumps off just before it reaches top dead center.

Yeah, it will roll 360 in any direction.
I just took the valve cover off.
I turned it by hand counterclockwise and then clockwise and the bottom isnot moving.
 
By the bottom are you referring to the crankshaft ? is the piston going up and down ? , Pull the spark plug and watch your piston to see if it's moving, it should roll very easy with no compression , you can put a rod through the plug hole and watch it move with the piston , if no movement you got major problems internal.
 
Bottom, i meant Bottom valve. It would not move up and down.
Top valve looks good.
The spark plug has been out the whole time.
Internal, meaning what could it be.
