You are doing part hydraulic part mechanical adjustment. If hydraulic
lifters adjust with engine running. To start engine loosen up adjusters back
to where you started. Loosen one slowly till you get a clatter, tighten to
no sound, then tighten half turn further. Make sure engine smooths out
before going to the next valve.
