Kioti CK27 door latch wont open from the outside

[Looking4new]

The door latch on my Kioti CK 27 is giving me a real hard time opening from the outside. I've taken the window dressing off the latch on the inside and found the latch adjustment button has a bolt with a recessed lock nut on it. I think a work around would be to drill a hole in the plate that actuates the latch on the inside and put a 1/4" bolt and nut and that would take up the slack. Rather than taking the whole latch assembly apart just to turn the plunger bolt out a 1/4". I think that would work, what do you guys think?
