Take a deep breath & post all engine numbers, everything from engine data plate as ILENGINE asked, possibly something simple like adjusting valves, thanks,

Take the mounting nut / bolt off the top of the crank and have a look at the flywheel key.
If both 1/2's make a square hole it is fine but if it is not dead square then the key is broken & the motor is out of time
