blowing fuel into a new engine is not reccomended unless yu know what you are doing. if you blow too much in, then the engine could hydraulic which is worse then running a few turns wiht out oil. if you blow it, then just watch the line till fuel just reaches the carb, not actually blowing fuel into the engine.
