Personally, I got to say I'd rather have a fuel injected engine, with a carburated one either a down draft of updraft, you face the possibility of an induction fire if you overprime, and you also have the possibility of carburator ice, you also have a carburator, more weight, more expense /incase you need to overhaul/ and more moving parts, basicly KISS, whereas if you have fuel injection all these problems go away, but thats just my opinion.
