The noise is most probably detonation of uncontrolled combustion of the mixture in the cylinders
The ignition timing should be no more than 10-12 degrees BTDC
max
If you have described the noise accurately, it occurs mostly on acceleration or when the engine is under load
it is from wrong timing or lean fuel/air mixture or incorrect fuel rating used for the engine ( octane rated at 89 instead of 92 +)
big end bearings start as a knock and gets worse with idle and acceleration
