Brown smoke

Has anyone ever seen brown smoke from exhaust? Saturday afternoon a couple of friends and I dug my old 48 buick(buidillac) out of storage for4-5 years and fired up the 500 caddy motor ,splashed little gas in carb and new battery, and it roared to life old gas in tank and all it had a little miss at first on left bank,a little fog and then the longer it ran the better it got then there it comes a real yellowy brown smoke,never seen nuttin like this before. (I'm 56) and my friends are 57 and 34 beats anything they ever seen,too. What's your idea on this. Thanks

 

Something other than gas getting into the combustion chamber?

 

i've never seen brown smoke either , i wonder if that old gas could be the problem? i'd drain the old gas and try some fresh ans see if that helps

 

Its rust

 

rust, from the exhaust getting some heat in it...

 

Yep.....the vapor form of patina. Bottle it and sell it to *****s. You'll be rich.

 

I think brown smoke means they haven't chosen the new pope yet...

 

Cl***ic!!!

 

BarBQ mice.

 

Seen it lots of times. Nice old rust!! It will go away after driving it and getting on it a bit. CHANGE THE DAMNED OIL!!!!!

 

stay away from the 7-11 burritos and you'll be fine.

 

thats funny right there, i don't care who you are!

 

### Isn't Steve Martin the new Pope ?? >>>>.
