Sounds like the flywheel key is deformed from shock. Remove the engine rewind and cover to get to the nut that holds the flywheel on. Remove the nut and flywheel. You can purchase a small engin universal flywheel puller cheap, install a new flywheel key and it will run great!

if I am reading this right it turns over by hand but not when you pull it? if it pulls but jerks the rope out of your hand then check the flywheel key. if it won't pull at all then I would venture to say you have an obstruction in the recoil that needs to be found

Pull rope on sears 5.0 lawn mower pulls hard sometimes or you pull the cord and the spindle does not always turn. I guess it's not catching all the time. What can I do for it ?

If mower has sit outside for a while the works in the recoil may be rusty and dry. Try some oil in all the working parts. See if that works for you.

My yard pro lawn mower will not start, when i try to pull start it the crank rope vets pulled back sometimes

Two things to check here, check the blade is tight, it acts as a flywheel so needs to be tight, second, check the flywheel key has not sheared as this will cause the engine to kick back as the timing will be out.

Starter rope on walk behind mower is hard to pull so mower won't start

Pull the spark plug out and give it a pull. It should pull VERY easily. You could have a vapor lock inside the cylinder and this will clear it. If it still doesn't pull easily with the plug removed then you've probably either bent the crank shaft or seized the engine, due to a lack of oil in it. Hope this helps. Best of luck.

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".

When I pull the cord, the string is hard to pull and recoils out of your hand about half way through the pull

Sounds like you have two problems. One the flywheel brake is not being released completely and second the flywheel key has been sheared. It is why the rope is being jerked out of your hand. The mower is out of timing and when the spark plug fires before it is suppose to, it jerks the rope out of your hand.
