Regarding it bogging down under a load, what gear/range are you using? In general, if it starts bogging down, I move it down into a lower range/gear.

Regarding the rpms, maybe check the throttle cable to make sure that it has the full range of movement. Move the cable with your hands (versus the lever) while it’s running to still if you can get it over 2100 rpm.
