Thats because the carb has to reach a certain vacuum level before the slide reacts . You can reduce that hesitation or reaction time by cutting one turn, one turn only! out of the long spring found under the slide diaphragm. This enables the slide to open at a lower vacuum level by lessening spring tension. Throttle response is more crisp. Don't be tempted to cut any more than one turn! Cutting too much removes too much spring tension and the slide bounces up and down with the slightest vacuum. This cause erratic unstable idle and/or the buggy instantly revs up engaging the clutch as soon as the motor starts.
