I feel kinda stupid about the whole thing so I ask you, the experts. Echo CS590 just getting broken in good and running decent, so i thought it was time to adjust the carb because it seems to be pretty rich. Got it all messed up now because the screws are not marked. I looked it up on the internet, of course, and the diagrams I have found seem to be backward to the way the engine is running. I can screw them both in to stop and back them out one turn to one and a half turns and it will start. I am not sure which needle is H and which is L and the way the saw reacts is opposite to what it should be doing according to the diagram I found. So to keep it simple which one is which. Many thanks for all assistance and advice.
