I need helpppppppp

[Chris!]

This fiesta is driving me mad, i really dislike it the engine has been "re-built" by the previous owner, i went to start it up for the 1st time since the "re-build" and as soon as it fires up it runs at full throttle even when your not touching the throttle pedal. Ive tried 3 different carbs and it does the same thing with each carb. can anyone help me

Air leak???? if the carb isnt opening, then how can it rev?? either your cable adjustment is holding it open, or you have an air leakwhich is letting it rev only thing i can think of
