Smoke from the carb?

[DoobieBrother]

Well I had an interesting find today. Went out to the old `68 to drive it back around to the driveway. Parked it and decided to pop the hood to WD40 a few things just for good measure till resto starts. Anyway I'm looking around under the hood and I see this little bit of smoke coming from an open line on the back of the carb. I'm guessing it's not a big deal but wanted to run it passed you guys. It was just a little bit wafting from it like you just blew out a candle.

FYI, this is a 350 crate moter that was put in about 10 or so years ago when it belonged to wifey's grandfather. They hung all the old original crap that came on the original327. So, it's an old 2 barrell Rochester carb you're looking at from the driver side. Here's a couple of pics.



Further away for perspective...
