That sounds a lot like a problem w/the accelerator pump.
One thing you can do is w/the engine OFF, take a flashlight and look down the primary throat of the carb and open the throttle. You should see gas squirting just as soon as the throttle starts to open. Should be a stream of gas coming out, not bubbles and drips.
You didn't say if you have to pump the gas a lot to start the engine when it's cold, but if it's the accelerator pump this wouldn't surprise me.
Another thing to check is to be sure the choke is opening all the way once the engine is warmed up.
