Give it a good thorough cleaning and lube. Then try chrono'ing again.

If you've done a full teardown and cleaning, this includes removing the valve, reassembled properly and properly lubed, you probably either have a weak drive spring or worn o-rings. Try replacing all internal o-rings. If that doesn't work replace the drive spring.

Before replacing anything, inspect the bolt, power tube, and drive pin (the rod inside the drive spring) for indications of bending or unusual wear. Replace bent power tube and/or drive pin. If the bolt is showing unual wear, try to determine the cause if the power tube isn't bent.

Also, when the gun is gased up, listen closely to the area around the valve. If the input line is leaking, obvious correct it. If it sounds like it's leaking down the barrel you have a probable problem with the valve. When you lubed, did you run any through the gas line to lube the valve internals?

about 75 degrees out.   put in 5 drops of oil into the asa before I gassed it up.  the guy at the garage sale said he had just had all new o-rings put in it a month ago.  don't know if he was blowing smoke or not.
