adjust the pedal stop to where your driver is comforable with it fully depressed and adjust the throttle cable until the carb is completely open. To be honest, I’ve never measured the amount of travel. Many pedals have a couple of positions for the cable and you can used them to tune the rate the carb opens. When there is no pressure on the pedal, there should some slack in the cable. Be more concerned about the brake pedal than the gas. Your driver will find a way to get the gas pedal all the way down. Be sure the driver can stop the kart. Use a return spring on the gas pedal.
