you must do a better job at the noise...could be issues with ignition..

the noise may be the pistons,,,,pre-ignition,,,this may be caused by excessive carbon in the combustion chamber...

this may be due to a bad carb or excessive crankcase vapors getting into the combustion chamber...


changing plug temp to a hotter plug may help...one range only..
