Whether or not an Onan needs to be choked to start it may also have something to do with it's altitude setting.
Our Class C motorhome's Onan generator has an altitude adjustment knob on it.

This may make a choke necessary to start it if one doesn't notice the too-high setting of it's altitude adjustment knob. Also, running one's Onan at lower altitudes with it's altitude knob set by mistake at a high altitude runs the risk of burning out it's valves.
