Just curious, when do you use the choke to start your 912ULS? The manual says:

"If engine in operating temperature, then start the engine without choke" (operator manual page 3-7)

I live in the desert where its often 90-110F on a "cold start". I was using the choke as instructed since the temperature was not up to the operating range but I was finding the starting was not as smooth and easy as it should be in a rotax. It even flooded once rather than starting. I then stopped using the choke on a cold start when the air temp is above 90F and its started smoothly every time since. Has anyone else noticed this? At what air temperature do you stop using your choke for a cold start?
