Trying to identify belt by the engine numbers will not work.But you can measure the belt, by making a mark on the outer edge, and measuring from mark back to mark, with a tape measure. The outside dimension is the belt length. The width is the back side of belt measurement. So belt example would be 43X1/2 inch. And that is the way belts are sold. Do you have a model number for the go cart? That would be what in needed to see what belt was on the unit.
Also any auto supply can measure the belt and give you a replacement.
Did you find what you needed? Thanks,
