Small Engine Troubleshooting Problems? Ask a Mechanic Now.
Is your engine a Briggs and Stratton brand? I need to confirm something. Are you saying that your rope is wrapped around your blade?
Thank you for this information. Would you like for me to attach a video for you, that will show you how to remove your recoil assembly.
Do you know if your engine is partially locked?
When you pull your rope, does your engine spin during the 12 inches as you are pulling your rope?
There is a possibility that you have some internal engine problems, rather than problem with your rope recoil assembly. Remove your spark plug again. Check to see if your piston is going up and down.
After you remove your spark plug, shine a flashlight into your spark plug hole, to observe to see if your piston goes up and down. you can also insert a screwdriver into your spark plug hole. You may need to get someone to pull your rope for you.

The engine in the video is not 100% identical to yours, but the procedures for removing your assembly are exactly the same.
Check your piston movement first. After you remove your recoil assembly, try turning your flywheel by hand. If your engine still comes to a stop, then your engine is very likely partially locked.
It your engine is actually locked, you will need to remove it from your frame, and disassemble it, to determine what is broken inside. Check your oil to see if it is low, and if it smells burnt.
If your oil is too low, or none at all, this can cause your engine to lock.
Make sure you pull the bail on your handles back, before you attempt to turn your flywheel.
Are you familiar with making internal repair to an engine?
Your engine is definitely seized, due to a lack of oil. You will know for sure, after you disassemble your engine.
I would like to give you my honest opinion.
Due to the low oil conditions, I feel you will be better off if you either replace your engine, or invest the cost of a new engine, in the cost of a new mower. It will be very costly to get someone to correctly rebuild your engine.
You are very welcome! I truly hope all turns out well for you.
Weigh your options first, then make a decision from there.
It has been a pleasure working with you.
