ok so i installed a new pipe, and i took out the carb changed the reeds, jets and then put it back in the blaster and the slide was not in all the way but there was probably a 1-2cm gap, is this suppose to go down all the way? i started it and it reved automaticly without touching the gas, im pretty sure it is that the slide was not down all the way but is it suppose to? i also played with the air screw did nothing
