Sounds like clutch noise to me. If you like tearing it down, might as well do it again and check the basket cushions and basket fingers for wear. You can also remove the clutch all together and fire it up for testing. The clutch generally has some noise. If it gets a bit quieter when the engine is revved, that is likely the case.

It will be the clutch cushions. Mine did that, was told it was the crank, bought a cub, 4mm crank, spent close to 4000 dollars, and then found out it was the clutch cushions.
