I had 12V on the one post, but nothing happened when I turned the key to start it. It ended up being a loose connection going into the relay/fuse box. Far right connection doesn't seat the whole way. I have it ziptied in place for now, but would like a better solution. With the wiring fixed, I did a valve adjustment and it fired right up, but seems to be lacking power on hills. I just ran it around my yard real quick and definitely feels like it's lacking power on anything other than flat ground. I guess I'll have to inspect the clutch next.
