Tuning Daisy 880/922 help.

i just bought a new piston rod with seals for my daisy 922(same as 880 but in .22).
put it in but now my pump handle wants to come ajar VERY EASILY. i noticed that the pump handle has pressure the last 2” or so before it closes. i cant remember if it did before. never had any issue before with the pump handle not wanting to catch. any ideas for me? thank you.
and HAPPY THANKSGIVING.
