Welcome to JUST ANSWER small engines, let me try to help you !! Is it drive line shutter? Or do you feel it is the engine? The shutter at full speed is usually either the drive clutch or the driven clutch. If spark and fuel are good, also this is four cycle engine, which could need valve adjustment. The engine has a rev limiter, which could be bad.
