I have an early 260 equipped with 240 carbs. Yesterday I noticed a few drops of gas under the car directly under drivers side floorboard towards the front. A quick inspection revealed a gas leak from the underside of the rearmost carb. Gas is apparently running down some line to where I noticed the drops. I haven't had a chance to fully investigate the problem yet and I am looking for some pointers and advice. I bought the car recently and am admittedly no expert Z mechanic. Thanks in advance for any help/experience you guys can provide.
