I've got a video of a "0" Turn with it installed. The operator turns it over a few times, then gives it throttle, it starts immediately, backs it back down to idle, engages cutting blades at idle with no hick-ups. Then with the cutting blades engaged, dumps the throttle up to full throttle with no hick-ups, then backs it down. Runs more smoothly than any small engine I ever heard, didn't hick-up when engaging the blades at idle, didn't hick-up when dumping the throttle with the blades engaged. I need an email address to send a large video, 85.7 mb. 33 seconds long .mov file to. I can't post it.
