Welcome to the forum !

You probably already know and have checked
Your engine may lack or have excess fuel
Adjust the amount of fuel around the position where your engine want the to run, adjust only a few degrees and check, ...continue until the engine runs
- The height of the fuel tank vs the carburetor is also an issue.
- Check the friction, too much friction is also the cause
- If all of the above tests and the engine cannot run, rebuild the cylinder and piston. Good compression does not mean it will be compressed enough to sustain engine combustion

The prop looks small for that engine. What size is the prop and the engine
