Loosen the valve rocker and pully the push rod out. Is it bent. If not, reinsert it and holding pressure against the top, turn the engine by have and see if it goes up and down. If so, reinstall the rocker and set the valve lash at .005" just a bit after TDC. One thing to check after you get the valves running correctly, is to check your belt routing. Especially if you have the stacked pulley in the rear. It's very easy to get the 2 belts on the same side of the center wall.

Try the simplest first. If does seem to reason that changing the belts would cause a major overhaul. Does the starter turn the motor over? Does the motor turn over and not start. Check for spark.

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.
Check the routing of the belts. Charge the battery, anything less then 12 volts starter will not work.

sheared flywheel key if top turns but not bottom. pull shroud off and verify if crank is turning with flywheel, if so then crank is broke, or you lost key on bottom pully if you pulled it off.

did you check to see if you moved one of the interlock switches or loosened a connection, since you were doing belts, I would look at the obvious stuff that could have been bumped or hit during that before I suspect the engine. If it's more than one it's harder, but you can bypass each one and see if it turns over. Or you could just jump the starter motor and see if it turns over.

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

Are you aware that there is a safety switch that keeps the engine from starting if the blade switch or blade lever is not completely off. Are you sitting on the seat when you try to start it? Unless you sit on the seat it will never start as these is a safety switch in the seat.

That’s exactly what I was thinking. Safety switch

Sounds like sheared flywheel key if bottom doesn't turn with flywheel, Could one of the magnets come loose, saw that already, explains the lockup in one direction.
