What happens here

Now, fully reassemble the gun. Slide the handle back onto the gun, aligning the internal pin within its slot. Screw the handle until it is hand-tight, then use the 5/8-inch wrench to fully tighten it securely. Next, lubricate the inside of the gun body with WD-40, focusing on the packing area and any threads. This helps ensure smooth operation and prevents paint from drying and sticking. Drop the cleaned spring back into the gun body. Carefully insert the needle and seat assembly from the back, ensuring it slides smoothly and aligns into its proper position.

Goal: Fully reassemble the gun's main body, including the handle, spring, and needle assembly.

Going to take and lubricate the inside of the gun with some WD40. Put a little bit on the packing or threads prior to assembly. I'm going to drop that down. And you'll be able to see the slots. There's two slots inside. It's going to drop down, slide in, and it'll slide into the needle, pops out, and
