Maybe the op already has carbs or wants carbs ?, as per his question.
You've obviously never seen a reece fish carb, carbs can still give ace results, the op might be a millionaire and not need to care about fuel costs.
I know of peeps still on carbs, doing limited miles some on track cars others are every day used cars.
The point is carbs can be made to work perfectly well, and run perfect start perfect etc, no they won't beat a efi, but that wasn't the question.
