Raptor OS MAX .50 SX Engine Tuning

I bought a used Raptor .50 and I want to tune the engine my self so I know the helicopter inside and out. I want to know a good starting point, so if I lean out the engine until the needle is closed, how many clicks or full turns out would be a good starting point?

1.5 turns out on the top
idle mixture set so the screw is inline with the barrel of the carb.
