What causes the choke to open on a Honda lawn mower?
After the engine is started, heat from the engine warms up the WAX CYLINDER (yellow) causing the wax to expand, pushing the PISTON (purple) out and forcing the CHOKE CONTROL ARM into the opposite direction; the CHOKE PLATE is then opened, allowing more air to enter the engine.

Why does my Honda lawn mower only run in choke mode?
Wouldn’t hurt to go through the fuel system from tank to line to carburetor including fuel bowl under the carb. Could be some dirt or water in the float bowl.
