You can't adjust the valves in these motors, but you should thoroughly check the heads first before re-ringing it.

Check for leaks, cracks, straightness, broken springs / valve stems. You could also freshen them up by tearing them down, clean off the carbon, lap the valves in and install new valve seals.

The no spark will be a separate problem.
