#1 and #2 are ill-formed in my opinion.

#3 and #4 are possible. However, “a kind of ice-cream” can be read as if the stuff produced is not quite ordinary ice-cream, which may not be what you mean. In #4 you could argue that “any lever” does not logically make a “different” kind of ice-cream flow, but possibly that is nit-picking gone too far.
