Hey whats up guys, I was driving on the freeway today and when I punched it to speed up and pass a guy, a puff of smoke came out the exhaust pipes. What do you think is causing that? I'm thinking it might be the valve stem seals but do any of u have any suggestions?

Thanks in advance...

Well, I've been having problems with this Holley carb ever since I got it. I think it's running rich again, wasn't running rich for the last few months, then all of a sudden here it goes again....I'm just stating that to say I wouldn't be surprised if the float is sticking open. Do you think I have to take it apart and clean it? I have another Holley carb in the shop that I'm thinking of pulling apart and rebuilding and selling the one I'm using now.
