As long as you do your job managing carb heat per the relevant POH, R22 or R44 (and they are different in this area, so go read carefully), you should not have a problem. Just like you shouldn't have a problem in any other carb-equipped piston engine aircraft. Get behind the power curve (hah, a pun!) on your carb heat management and you could have a problem. I'm not sure when it came into use, but newer R22 and R44's have a carb heat assist system that helps manage the carb heat. See Section 4 in the Raven I POH. Also Safety Notice 25.
This is one thing about the G2 that I am jealous of, which is the electronic, automatic carb heat system on that aircraft. It would be very nice to see a similar system on the R22 and R44 Raven I's, and a power limit indicator to go along with it. I've heard rumors that Robinson is working on electronic engine instrumentation. That would be a very welcome addition since Robinson has already fully embraced Garmin glass and Genesys HeliSAS for those willing to pay for it.
They can do what they want to the 44, but I prefer my 22s to be simple and Spartan. Just an old Beta ('cause I hate that carb heat assist) no glass, just the basic old five pack, simple transponder, and radio,...don't even need a gps. In fact the only upgrades I like are a trigger/voice activated mic, and the newer, white map light!
