ring break in time

This is on a Mazda B2000 so they do drive in with a hammer. They are only $2.50 a piece (ID is already finish reamed) so I'm gonna try and replace them myself. This diagnosis makes sense as the closed valves sealed up fine, it was the lean mix in #3 from the bad guides that would not light off, theoretically...... I even put a Mallory HD coil on it and almost put a Hi-6 box in to see if I could force it to fire but I didn't want to hack the Hi-6 harness for this POS.
