Ok got the screws for the butterfly. Reassembled everything and now it won't start. I assume it must be something to do with the safety switch in the deck arm. Can I cut and spice those wires together? It has been touchy all along and I'm tired of messing with it. Are there other safetys? Does the hood have to be on? The rear PTO arm is in the center position. All the wires are in the corect locations and clean.
