Need to let the mainspring down but can't find the click. Anyone know how to do it. Have the crown to hold the tension but it's fully wind so tight. So if i just remove something i am sure something will break.

Remove pallet.immerse in mineral spirits.let it wind down.

Your approach works, however, I apply slight pressure on an outbound gear to stop unwinding before dropping in the liquid, just wondered how you keep from unwinding before immerssion. Regards

Most of the time , if the watch has stopped , it wont start moving until immersion.If after removing the balance and observing that actuating the pallet fork does not cause the gear train to move I will  remove it and immerse. If not I flood the gear train with motor oil. It will then either move slowly or not at all.It all comes out in the wash, so to speak.
