What's an example of something that can be recognized with parser combinator but not PEGs?

Do parser combinators have the notion of arbitrary lookahead or backtracking?

Parser combinators can do look-ahead and backtracking, yes. You definitely pay for it in efficiency however (especially look-ahead).
