A sure tell tale sign of carb leaking and front bearing worn out is when you find lots of oil stain on the carb neck and on your chassis respectively.
Sometimes this can happen. Have you taken out and unscrew carb from the crankcase before? The process of putting it back in can somehow not be correct.
