George;

I go with Larry on this one. I just did mine for the first time. I made myself some wrenches by welding two together and then bending them. But I broke mine twice so I will buy the proper ones. It makes the job very easy to do with the proper tools. It never ceases to amaze me how easy these cars are to work on for most things, but, of course most well built machines are.
I believe that the settings are
Exhaust 0.35mm
Intake 0.10mm

Enjoy and just ask if you need more advice. This site is the best there is.
