don't change the sear rod, it's always something else, not that. move it back to exactly 1.98in and explain the problem from there.

i had the same prob. if a .220 is just leaking then oil it up.. or use a .215 and oil it up. it will work

it was the on/off valve. i guess the last time i took it apart i left the teflon oring off.
