That sounds like the accelerator pump is malfunctioning or maladjusted.

When you open the throttle by hand while looking and listening down the carb (engine off) you should hear and/or see jets of gas spraying into the bores. If not, then you need to get a kit from the parts store that will contain a new little pump piston. You just take the top of the carb off and lift it out and replace it. The hard part might be getting the top back on with all the dangling needles and rods down into the correct locations but it can be easily learned how to get it right.

If you do hear/see spray, then maybe the setting is off. there are different holes that the connecting arm to this pump can be attached to. Very easy to set it to the inner hole for more spray.

Of course you should also make sure that you don't have a vacuum leak anywhere.
