Yea! HUH? The same problem that you seem not to understand. Open the LSN 1/4 turn and your problem will go away. Or keep on running your engine the way it is and buy a new one and start the whole headache over again!
Your still too lean if the engine doesn't idle down. Open 1/4 HSN turn until it's gone. It should not sound like it's screaming. Again this comes back knowing factory settings and how far you can go on the HSN to max speed. Usually 1/2 turn tuning is all you have . Such factors :temperature...
