Yes I think the culprit is the carb. It has a small leak on the pass. side outside of carb, after I shut the car off it seems to drip fuel in because I can see vapors coming out of the top and if it sits for a few minutes I have to hold the gas pedal to the floor for it to start. And I was driving it the other day around the block and it wants to load up bad and smokes black, if I rev the engine it will straighten up for a little bit. I have tried to adjust the carb with no luck.
