The end of a .006 feeler gauge is ground to .004. For a loose .004 at the intakes, the end will move freely, but the .006 portion won't go. This means I am between .004 and .006. For the exhaust, I set them so the .006 just goes through. I get my go/no-go feeler gauges from my local Snap-On dealer. I am sure they can be purchased at many other places. They just take a lot of guesswork out of adjusting the valves. -- Russ Wolfe '71 Fastback AT '66 Fastback MT (IT RUNS) russw@classicvw.org http://www.classicvw.org ------------------------------------------------------------------- Search old messages on the Web!
