Good comments,
I agree, its a little wordy...
I stole the diagram from somewhere else...I guess I could edit it
Looking through the previous valve adjustment post and the tech article most posters seem to refer to the "Shim" as a "Gauge" I was trying to use a technical reference to the actual tool used.
Additionally most post refer to the .004 as the most common tool, of course anyone can edit the picture to suit there own needs I haven't copyrighted it, and in fact I have stole everything on it from somewhere on this site.
The magnet is just paper thin magnetic material that has a sticky side to it to affix a decal, it can be trimmed to the same shape, my wife bought it from the stationary section at W-mart.
I think I put the 120 mark in the wrong spot.
I will refer to the initial post as a prototype and see where this post leads for the final edit.
