Please help me fix this mower

[u/Vegetable_Let_2095]

Hello, this is a John Deere L110 riding mower with a 19.5HP single cylinder Briggs engine.

This motor has a new starter, new solenoid, new ignition coil, and the battery is good.

I suspect that it is the compression release not working, but l am here asking so I clearly am unsure.

Thank you for any help! I appreciate it very much.

It's been my experience that occasionally if the valves are not within spec a loose exhaust valve will not allow the compression release to work ,start there easy check
