good guess , look online for rebuild kits.

You may disassemble the channel where the nail exits. I have found issues where a burr causes the driver to hang. My issue was on a different type gun.

it has 2 gauges , one for tank pressure and the other is the regulator output. tank pressure is on left. The pop off is starting to release because is worn and should be replaced. if unit is only making 30 pounds on tank gauge you have other problems . If that is true personally i would replace it. https://www.ereplacementparts.com/porter-cable-c2006-type-compressor-parts-c-129_1662_16249.html

you may have to rebuild it again. inspect nail gun piston cylinder to ensure that it is not worn or scratched. Is the gun lubed before each use and periodically under heavy use?.

The nose tip is most likely stuck in the ready to fire position from too much force being applied when nailing. These guns are small and sensitive to forces being applied. Try bumping it to see if the nose tip is retracting and compressing with each bump. Unplug and unload the gun before trying to pull the tip of the nose to retract if it is stuck. Check for foreign objects obstructing the trigger and safety mechanism

check ram is returning /retracting all the way --debris in feed rails --damage feed rail

You need to oil the gun. Put a drop or two on the nail driving mechanism too.

Uses 23 Ga. headless and slight head pin nails from 5/8" to 1-3/8" length

The fr350a is completely different from fr350. The fr350a is completely modernized framing gun as compared to the retired version. I do not like repair kits because you are replacing parts that are still good. Instead replace parts as needed. If you state the issue you are having I may be able to recommend the actual part needed. If however you do not have any major air leaks, a lube job will make the gun work great. Use white grease or nail gun oil. Good luck with your repair.

Odds are you have a brad or part of a brad stuck in the slide. Use a flashlight & another brad or paperclip to remove the piece of nail that is blocking the slide.

The part that you are looking for is most likely the "piston stop." this part can be found at Dewalt service centers as they own Porter Cable. Also some Ridgid nail guns use the exact same parts as Porter Cable. Good luck with your repair.

I find that the trigger valves in these guns are reliable and that most problems with random fire is lack of lubrication and adjustment of the safety foot. Assuming that air does not leak when you connect air supply and leaks from trigger when attempting to fire. This indicates a lack of lubrication of the head valve. Remove the head valve and lube with white grease. Test the gun, of ok then you are done. If no joy, then check safety foot for adjustment. How to test if the safety foot is the problem. Remove the nails, remove the trigger leaving exposed the trigger firing pin. Adjust air supply to 100 psi and connect to gun. Assuming no leaks quickly depress the trigger valve pin all the way in. If the gun fires then the problem is with the safety foot and or the actual trigger is not pushing the firing pin all the way in when attempting to fire. Make adjustments accordingly. Good luck with your repair.

I never use mine in the driver setting, always in drill mode. The reason is the clutch won't last and while the motor rotor revolves, the chuck head will not have torque and won't work no more.

Moisture and oil in small amount is normal with oil type compressors, a by product. If there is no air leak between the pump and tank, suspect worn piston rings, worn out faulty valves, loose pump head.
