More info on the car would be a great help. Also, there are hundreds of posts on that subject. If you do a search for "Carb bogg" or any derivation of that and it should come up with some good reading material for you.

Also, if you look Here you will find some info on this subject that I believe will be related to what you are going through.

Re: Carb

Sounds like the accelorator pump could be bad. Try a full on rebuild. because if you romp it at the carb it reves but with the foot inside the car you kinda have less control.
