Don't go junking the choke just yet. It is very useful for choking and can even be used as an engine kill. A good friend of mine had a stuck throttle on his Patty Wagstaff and ended up tearing up the plane trying to land it with power on. Had he had a servo actuated choke, he could've killed the engine in flight.

Especially for the rear carb Ryobi, manual access to the carb throat for priming can be difficult. I doubt even TOC-class pilots can notice 1/4Oz difference.
