The old one (the one on your car now), will be stamped with a number. Take the screw out, being careful not to drop it down the carb., and pull the nozzle up. Look close and you should see the number on it.
If your car is not stumbling, or hesitating, on take off, put the same size back on. If there is a gasket, make sure to replace it.
Sometimes it looks like one side only dribbles fuel and this is normal. as long as it runs good, it'll be OK.
