yeaaaahhhh...:huh What would cause a sheared flywheel key? I just don't understand the fact that it was running previously with the DS kit - kinda makes me lean towards wiring? Yes, the valve was not bent - He initially thought it was, but that was prior to removing the head to find the screw. He said the valve was surprisingly not damaged and seals fine. Choke assembly and carb are in good order and clean. Spring is tight, etc. This def crossed my mind - after what I've read between here and TT, I was thinking along the lines of this knowing you have to kick this machine like you mean it. But I would think between the drill and the car-powered roller to try and bump start it it would fire.
