T/C Encore Endeavor Trigger

[xpert07]

Ok folks, I replaced the trigger plunger on the T/C last nite and cannot get the hammer to set. I've had this apart several times for cleaning w/o problem but not this time. Im certain all the parts that came out went back in too. 
Any Idea's at all, the schematics I have are poor at best. I guess the trigger sear isn't catching.... I'M NO GUNSMITH, AND MAY JUST NEED ONE! LOL

Have you tried to back off the hammer spring nut to "not so tight"?
