For a beginner, lets adjust the valves to right in the middle of tight and loose, or 0.11mm. Find the guage that reads 0.11mm, don't worry about the other numbers on the guage, it won't be used.

Take the 0.11 guage, and slip between the intake valve and rocker. If it slides in and out with slight resistance, you're good. If it slides in real easy, or not at all adjustment may be necessary.
Thanks for the help and info really appreciate it. What's got me is none of the gauges have 0.09mm, 0.11mm or 0.13mm on them!
