I stand to be corrected but I don't think the push-to-choke facility on the remote actually does anything on an opti - as Brian says ; blackbox electronics, no choke.
You must never lift the fast idle lever to start it either - only use (if necessary) once it is running. The engine is slower to start than more conventional 2 strokes - it has to make a full revolution to pressurise the injector rails etc before it will fire. They do start so easily though that it is easy to forget to squeeze up the primer bulb beforehand - most times it doesn't make a difference but after towing I do find it has gone soft !!!
