Re: replaced leaking trigger valve wit new valve kit.
I have seen many small bostitch guns all with different problems that did not shoot nails. Both of your guns have simillar triggers. You might try the trigger valve from the gun that works to see if that is the problem. Most no fire situations come from faulty trigger valve. The trigger valve used in your guns has a part that stays in the body of the gun; be sure to replace both parts. If still no fire check the following:
Remove the head and check if the piston/driver travels all the way down the cylinder with the tip of be blade showing at the nose. Some piston/drivers have a grove that must be aligned.
Check that the headvalve travels into the head and returns. Push the valve in with your thumb then cover the small vent hole at the base of the head where the gasket sits with your finger and release your thumb. The headvalve should be held in with vacuum then pop up when you remove your finger from the vent hole. If the headvalve does not stay pushed in with the vent covered, the orings are leaking and can cause the gun not to fire. Try lubing the headvalve with light grease such as silicone lube. Do not use bearing grease. Silicone lube is available in small amounts at plumbing supply/lumber outlets such as Lowes. It looks like wax feels like shortening.
Reassemble the gun and check your work. I test the gun with-out nails and without the trigger installed. Just place the nose of the gun on a piece of rubber, (I use a piece of heavy garden hose rolled up tightly into a coil) and press the trigger valve pin with your finger. The reason that I leave the trigger off is that sometimes the problem is caused by the safety mech not pushing the trigger pin correctly. enjoy

SAFETY FIRST! Disconnect from air supply.
Pull trigger to make sure not "loaded"
- Here's what I would do.
1) Open magazine and remove stick of remaining nails
2) Try to remove jammed nail with pliers, pointy tool, etc.
3) Use allen wrenches to dis-mantle head until everything comes apart and jammed nail falls out.
4) re-assemble, cleaning and oiling at the same time.
Once done, re-connect to air supply and test.
Hint. A 2 inch nail can take some effort to penetrate, especially a knot in hardwood. Make sure you are using adequate pressure; that is the high end of the recommended pressure.
If your using refills that have wire holding the nails together.
Check to see if bits of wire, debris is collecting in around the striking hammer. I switched to paper and never looked back. Must have gone through 5k worth of nails and rarely jams. Other things to check,
1. Check the striking hammer, make sure it is not bent or damaged.
2. Check air pressure, Low pressure can cause jamming, misfires.
3. If the tool needs pneumatic oil, 2-3 drops before you start good rule of thumb.
4. Check spring return. Sufficient pressure must be maintained or the nails will not feed properly. Misfires, incorrect feed, jamming etc.
I had a Hitachi brad nailer and it was horrible. Fire 1 brad nail would jam or misfire. Did everything I could think of nothing worked. Put it up, got a Rigid brad nailer and never looked at the Hitachi again. :)
Sometimes you just get a lemon! (PS I understand you have a framing nail gun. Brad nail gun above is used for an example)
Hope this helps
Most of the time it is a bad o-ring. Seals, gaskets, and O-rings get dry from storage and/or use without oil. Most people oil their tools before use when in fact it would be better to add tool oil just before storage. Take the back of the tool off and inspect the seals. If they are dry inside then order a new o-ring and gasket kit from the web. The worst thing you can do for any air tool is to add WD40.
You did not mention the brand or model of your gun, however, you can determine the angle needed by placing a straight edge in line with the path of the driver and measure the angle from this edge to rails.. If the straight edge to the rails measure 90 degrees or makes a right angle, you need "0 degree" nails, if it measures 80 degrees, you need "15 degree" etc. Most generic nials 15 gauge nails will work. No need to by branded nails unless your gun requires an unusual angle. Good luck.
Sounds like a trigger seal. I assume this is an oil-less brad nailer as that is the standard. You should be able to find the seals at any local hardware store including Home Depot or Lowes. If you can't find the portercable O-rings just grab the random assortment from Bostitch which is usually readily available. Refer to your parts manual for the correct size/gauge
Porter cable makes a number of brad nailers (18 gauge) that very quickly suffer from the problem that you are having. You did not mention the model number of your gun but if it is one of these, (bn125a, bn200a, ns100a) kit # 60061 will fix the problem. It costs between 25 and 30 dollars. Google that part number or order from www.dewalt.com. Dewaltowns the porter cable brand. Before you order the kit, check that the driver blade is not bent and stuck. The driver should travel freely down the cylinder. When you install parts, use Danco silicone grease to lube (availabel at Lowes in the plumbing department) If your model # is different from those mentioned above, please email me and I will recommend a repair.
