BTDT, we all have aw shit moments sometimes, not the end of the world.
Next time:
A shorty screwdriver custom ground to fit snugly into the jet hole slot, lightly put in a vice so it cannot slip out of the slot, then turned with an adjustable end wrench ( crescent wrench) usually does the trick of unscrewing the jet without damaging the jet slot.
Search the net and/or put a "wanted ad" here on OCC for an oem carb as others mentioned.
FWIW: I have had ones that refused to come out because of corrosion.
