Your nailer has a collar /vinyl seal that should be installed on the head valve and seats against the cylinder. The seal should fit very snugly on the headvalve. The plastic cylinder must not have any nicks on the surface or be out of round. The head valve has an upper bumper that needs to be inspected for cracks. To test the orings in the head for leaks do the following. Push in the headvalve with your thumb till it hits bottom then cover the small hole at the mating surface of the head with finger then release headvalve. Suction should hold the headvalve in for a moment. If no suction, replace the orings. Parts and item list are at WWW.toolpartsdirect.com . Enjoy

SOURCE: ring burns up low compression
sounds like you are running to lean,whenever you alter your exhaust system you must rejet your carb. when you have jetted correctly your spark plug colour should be chocolate brown. white or gray is to lean black is to rich.Change your jet to a larger size,install new spark and take it on a short ride at full throttle stop and check plug colour. repeat this till plug colour is correct. hop this helps james

I had a very similar problem with a stihl 029 farm boss.I did everything you did except I took it to a shop to do the piston and ring replacement. When I got it back the first time it would run for about two mins. then die.I fought it for a couple of weeks then took it back and expressed my displeasure. Then checked it all over and replaced piston and ring again and it runs great. They told me they could not get the right compression with the first one and thought the groove for the ring was cut to deep.I hope this is of some help to you. Thank you.
