They both say they have a bigger crank bore, and though glow plug isn't exactly engine specification it is the same on the exploded view.
The only thing that make any real difference is if they have changed the crank in timing or bore etc, all the rest is the same between them. The carb could have slight difference in how it feels and tunes, but not in power.
But measure the timing and get back to us.
