I think you have your engine running way too lean and suggest you do the set up from the start again provided you have not overheated and damaged the engine already.

Reset idle needle and main needle to 4.5T and 2T respectively. Set up your idle up flight mode to have about 70% throttle at hovering.

Start your engine, let it idle and leave your finger on the crank cover, the temperature should be like your forehead or slightly lower and STABLE. Otherwise adjust idle needle to achieve that.

Try to hover, if not enough power, lean the idle needle to a point where you can barely hover, note the smoke trail.

Switch into idle up mode and note the smoke trail, disregard the power available to you. Start leaning the main needle ONLY to match smake trails between hover and idle up mode.

Once matched, you should have enough power to fly around a bit. This is your starting point for fine trimming. Temperature is not too high and power is not too low.

From here onwards, whichever needle you adjust, you have to adjust the other one in reverse to compensate meaning you can open up more idle needle for lower temperature but you have to lean the main needle to compensate for power and vice versa.

Your finger should always be able to be left on the crank cover for a couple of seconds before feeling any pain from the heat. If you cannot, your engine is running to hot.

Good luck
