could be the piston hitting the head or head gasket, carb wise they can be temperamental as well

Well if its rebuilt its not big end knocking so id tend to think top end as already said piston hitting head gasket may me remove the plug shine a torch down the plug hole and look at the piston crown see if its got a silver ring around the piston top for hitting something .

yes it is the top end i had a look at this one.
you will need to do the top end which is not a big job.
