I'm doing my first machine design for a project and I have a Honda GX160 combustion motor which has the following specs for power and speed: enter image description here

I'd like to use 0.24 HP at 2000 rpm. Is this possible? Or I can just get 2000 rpm at 2.1 HP as the NET POWER curve shows?

I'm using this motor because it's the only one I have available for this project.

(It would also work for me at 1300 rpm if it has at least 0.24 HP, but I don't think its recommended)

Thank you!

The chart shows the maximum power with the throttle wide open.

You can run at lower powers simply by having the throttle partly closed.

If you want to use a low power output like 0.24HP, you will probably need some sort of automatic control system to keep the RPM down to 2000. A simple throttle lever with manual adjustment might be too sensitive to adjust successfully.

A small engine like this may not run smoothly below 2000RPM. Any sudden change in the load might cause it to stall, unless you add a bigger flywheel to your design.
