The operator will monitor the engine performance and air/fuel ratio during the pull. When the engine quits making power he'll stop by taking his foot off the throttle. A skilled operator will not make a full pull unless the air/fuel ratio is proper or erratic. You will want to give your dyno guy a complete description of your build including cam specs if you have them, your carb, ignition, rev chip, and any problems you may be having such as hesitation. You may also want to have him pull your dizzy and check the gear first, as well as verify and adjust any timing issues.
A skilled operator will help you to solve your problems to make SAFE horsepower, and creep will break your motor.
