It may seem simple, but be sure that your battery has a full charge before you try to crank it. I would try that before I started tearing down the motor.

    If valves isn't adjust right, the compression didn't release.

Why does my Craftsman rider struggle to crank?

You said valves are OK, but did you mean not leaking and seating properly or correct tappet clearances? Check the valve tappet adjustment. If they are slightly tight the engine will be hard to turn over.

Turns over will not start

check for spark if you have no spark. you will probably have to replace the ignition coil

My lawn mower is trying to turn over but won't completely. we have replaced the starter, battery, and spark plug. why will this not crank and turn over?

It probably has a faulty starter solenoid which won't allow full amperage to the starter. Also the valve clearances need checking because if they are too loose the built in decompressor will not work and allow the engine to crank over. Regards Phil

Pull mower rope on troy built self propelled mower and it jerks it back out of your hand,hard,,and will not start

This sounds like the engine is out of time.
Usually this happens when the blades hit something hard and shears a small aluminum"key" between the crank shaft and the flywheel.
This is reparable. The little key is less than a buck. A person needs some skills to remove the flywheel to replace the "key".

I have a 24 hp briggs, model 445777, type

I believe this does have comression release. Make sure you're rotating the motor in the correct direction, as I think the compression release only works in one direction. Adjust the valve to .004 with the piston at TDC make sure it's on the power stroke. Turn the motor till intake opens, then when you continue to rotate crank, unitl valve closes and piston gets back to TDC. Adjust both valves to .004. Then do the other cylinder the same way.

Troy-Bilt Mower is running real slow like its clogged dont know not a mower expert, need help please before I take it to a mower expert.

If you can, check the flywheel key. If it is bent but not quite broken, it can cause slow operation. To do that, take the starter off the top of mower. Take off the big nut on the flywheel. Find a nut of the same size and place on the thread you took the nut off, but only a few turns. Hold the flywheel with one hand, lifting a little, and tap the nut with a hammer with the other hand. The flywheel should come off. Look at the key, it holds the flywheel to the shaft. If it is bent or broken, that is the problem. Replace it and go about your day! Good luck...Lee
