I had the trigger on my Wolverine do the same thing. I took it off, got a cheap can of brake cleaner at Wal Mart, and sprayed theh devil out of it. Over time the Timney triggers accumulate dust, grease, anti seize, powder, you name it, and it all seems to gather in that trigger. One reason why I remove the trigger when I clean the rifle. All of a sudden the rifle will not fire and sometimes will not cock on the pull cock models.

I sprayed that trigger until the brake cleaner ran clear out of it then shook it real good. Took it to an air compressor and using as much PSI as it could muster, blew the trigger assembly out as well as possible. After that I gave it a light spray of Sheath and it worked like a charm again.

Every couple times now, I pull that trigger and spray it out and then hit it with an air compressor again. Just to be on the safe side. If your triggers come out, it is not a bad idea to clean them like that. Just be careful with the brake cleaner if your trigger has a plastic trigger... Then I would take it to a sink and scrub it in some hot dish water, rince it in as hot a water as your fingers can stand, then air compressor it out and oil it back up..

Hope you get another chance at a big buck...
