Well I am going to post what I found so others might learn. 1. It's terrible getting old sometimes. 2. The dog at my homework. 3. I guess I forget things now. 4. There was no gasket between the metering block and the main body. 5. And I had it off twice before I figured it out. At least I am still able to figure it out. It's running all is well and life is good. Where is that smiley face. Jim
