140F Definatly too rich.Start leaning the Low end needle 1/8th turn till you hit 200F then see what the high end does. if it cools when you run it fast start leaning the High end till you stay at at least 200F. What is the air temp? If it is very cold there then a lower temp is better but 140F is a very cold temp for a nitro engine to run well at.After you have the high end running up to temp recheck your low end as it will probably need to go a bit richer now that the main needle is restricting overall fuel flow.
