Shemp, I thought you were going to provide the factory settings for these engines. I have been successful in finding the settings on the two SR's. I did not have any leakage probs. but did raise the tank on my test setup to level behingd the engine. Also. I'm not sure about the "pinch test". I pinch for the count of two, with the engine at ~8Krpm, it speeds up a little then coughs and catches up. soes that mean it's too rich? or too lean.
