What happens here

After replacing the needle and seat (or flipping the seat), if the gun still leaks or 'spits' paint after releasing the trigger, it might require adjustment of the needle tension. This involves loosening a nut located at the very back of the gun's handle, behind the spring. Use a wrench to loosen this nut by turning it counter-clockwise, making very small adjustments (e.g., a quarter turn). After each small adjustment, reassemble the gun, squeeze the trigger, and test for leaks. Repeat this process, loosening in small increments, until the leaking stops. Avoid over-loosening, as this can also cause issues. The speaker emphasizes that this adjustment is rarely needed, especially with a new gun or components, and is better to avoid unless absolutely necessary.

Goal: If leaking persists, carefully adjust the needle tension by incrementally loosening the rear nut using a wrench, testing after each small adjustment.

leaking with a new seat a new needle but you're going to take this off there's a spring this is what creates the tension on your trigger take this off and you're going to see a nut inside here that a little bit of tension behind there here's the spring and now here's that knot and what happens is with this new seat and needle in here if you release the trigger and you're still getting leaking on here it could be because this needle needs to be adjusted in or out now um logical thinking i would tell you that i want to screw it tighter to stop the leaking that is not the case what you actually want to do is loosen it up turn it the opposite direction tight to the right loose to the left so you want to counterclockwise you'd want to loosen it and that does not have to be adjusted very much i would just take my wrench put it on here or a socket and just turn it slightly tighten it back up and see if it leaks if it does loosen it up a little bit more it has to
