Help!! smoke from my '72 CB350

[72texas350]

I can't figure out what is going on with my CB350 engine. It was running perfectly fine then I went back in the house for about an hour, and when I kicked it started and pulled out of the driveway I couldn't even make it to the end of the street before white smoke started coming out of the carbs and the exhaust. All I did to the bike between when it was running fine and when it began to smoke was put some gas in the tank.

Any thoughts as to what may be going on?

Thanks,
Sam

Sounds like you've added too much oil........
