replaced the piston stop and brg washer
Watched a video on how to fix my nail gun. Ordered the parts they recommended a piston stop and a BRG washer. The BRG washer was bent. Installed new parts, works like new.

Good old YouTube came the rescues again. I was going to use the problem as an excuse to buy a new finish nailer but was on the computer and took a look to see if there were any folks who had the same problem. I didn't find the exact model - but the same brand had a few videos of repairs. (Porter Cable). When I watched the technician take it apart and then looked at the exploded diagram - I realized this was not a real complex tool. Interestingly, the part that the video tech had to repair was not broken on my nailer, but, hey - it was apart on my bench so I explored a little and in the place I was supposed to find a "piston stop" (a piece of plastic about 1/3 the size of a cork on a wine bottle), I instead found several ... like 20 pieces of crumbling plastic. Ordered the part and a few gaskets and $30 later ... it's firing perfectly ... 100% of the time. Of course I'm done putting up the floor molding in my daughters condo - but it's sitting on the shelf ready for my next mission.

Remove the top of the nail gun. Replaced the plastic piston stop and washer and cleaned all the parts. The plastic stop was pretty much breaking up into small bits that were clogging the release of air. Was not able to tell where the Urethane retainer that someone recommended replacing, from the drawing. Put it back together without it and is working OK now.

Clean all the pieces out from the broken piston bumper, and clean muffler. Install new bumper, make sure when installing top portion of piston not to dislodge o-ring, I did and it leaked air when I put it back together, took back apart and saw it had pulled out, just take time and align piston when installing, goes in easy and properly. Put back together, and shooting like new. Hope this helps anyone.
