Kraig and Lisa,
One other thing to check on the reverse issue that Lisa is having is the adjustable bracket. This is the same braket you adjust in the "neutral adjust" procedure. I was using Dad's #1 149 to till my garden. I made a couple of passes and was getting ready to start a 3rd and the tractor took off "wide open" forward. I pulled the lever back and nothing happened, and stomped on the brake and nothing happened. I idled back around the the garage, and what I had found was the bottom bolt in the bracket had vibrated completely off the tractor and the top bolt vibrated loose and the bracket fell out of position. When this happened I could no longer communicate with the transmission. When I put it back together, I had it close, but I could not back up at anymore than a crawl and had no power. I had to tweak it a few time to get it not to creep and to once again have reverse. Maybe you have a picture of this area handy. I know for an inexperienced user this would have been quite scary and dangerous.....
