Thanks for the reply Moses. I started tearing down the one that I bought off of ebay today and the only thing that I find that I'm not sure about is when I take the two screws out of the fuel regulator, one has a bigger ball in it and the other has a smaller ball with a larger ball on top. From what i am seeing there should be a weight on top of the smaller ball. This makes me wonder if someone rebuilt it and either lost the weight or whatever but put the larger ball on top of the smaller one for the same affect. As far as plates with numbers there aren't any on my original one or the one that I bought.
