I can't see the battery being an issue. The alt seems to put significant load on your little engine. With the belt removed the pulley is freewheeling and allowing the engine to rev up. Without the ECU systems most of us are accustomed to, the engine seems to have no way to adjust the idle. That's my guess. Maybe someone with experience with these older engines will have a solution. Good luck.
EDIT: it has to be a fuel thing, right? That's why you see more power in gear too. Your opportunity without the alt belt would be to adjust the fuel flow downward, no? Power-up your battery by plugging in. That would consolidate and expand the FE gain from eliminating the alt. Does that sound plausible?
