Hi
Maybe...There are two allen screws that adjust the trigger. One is for over travel, the other is take up on the trigger pull. If the one for the trigger pull is tightened too much, it will not stay cocked. If the over travel is in too far you cannot get it to fire. Maybe? If that does not do it buy some starter fluid, Maybe $1 for a spray can, go outside, and spray it all over inside. That will clean everything!!!! You will need to lube lightly, after, if that gets it to work.
Good luck
