I’m still assuming that you have a Leopard engine. If so, nothing is going to up and down in the carb. A slide type carb, which you should not have on this motor does have a plate the moves up with depressing the gas pedal. Your carb has a round plate in it that rotates on a shaft when the gas pedal is pressed. The resting position of the throttle plate closes the large opening thru the center of the carb. When pressing your gas pedal, you see the linkage on the outside of the carb move.
For now, your best bet is to let some one help you that can see and touch the motor.
