do all R44s have throttle governors ?

To my knowledge the R44 Astro has a carburetor......and it surely was cold that day.....
Not saying the pilot didn't use full carburetor heat before descending but if he didn't, then on short final, the 'throttle valve' could have been partly blocked with ice, restricting fuel flow, the throttle will open more and more to desperately try to get more fuel flowing (hence why it's a good thing to keep your hands on the throttle so you can identify it if you missed it on the gauges).
All speculation of course but it is a rumour network.
