[Elecraft] I'm Stuck!

Hi,
I am in the process of building my k2, sn 2884 and have reached the final
alignment and test. I decided it was a good time to install the stability
mod so that's what I did. After doing so, I ran the CAL FCTR and that's
where I ran into problems. Before mod: 4916.94 - 49.26 = 4.48; after mod
4917.12 - 4913.73 = 3.39. I added an 82pf cap across c174 and the result was
4917.08 - 4913.35 = 3.73,not much improvement. I added a 200pf (max size
recommended) and I get
4917.00 - 4913.27 = 3.73. I calibrated the internal counter to WWV and am
confident
that it's right on. I've rechecked the component values and they're correct
and I marked the old xtals when I removed them so I know they're not back in
the circuit. Any ideas guys??? Could I take my old L33 toroid and wind a
higher inductance coil?
thx
