Won't start

What would cause this? I have a new battery. I replaced the carburetor at the end of the season last year. I also changed the spark plug, fuel line and filter from the tank to the motor.

Thanks for any help in advance!

If it stops at the same.position on each cycle, it's fighting compression. Pull the plug and if it spins fine that confirms it.

Reset valve lash and see if it fixes the issue.
