hi brad
i just did this on mine.  follow "the rule of 9."
you want to adjust the valve (it's called) that is fully closed.  to determine which is fully closed, the rule applies as follows:
rotate the crank (best done by hand with a 1.125 inch socket on the big nut on the end of the crank, with spark plugs out) until the first valve (the one furthest to the front) is fully open.  you'll know it is fully open when the pushrod reaches its zenith, or highest point.  when that happens to the number 1 valve, then the number 8 is fully closed (1 + 8 = 9).  you'll need a flat screwdriver, and a 14 mm box wrench.  place the screwdriver in the slot atop the pushrod, and back off the nut.  the rocker should move freely.  then slide a feeler guage (.017 in.) between the top of the valve and the rocker, and snug down the slotted thingie atop the pushrod.  once snug, tighten it in place with the 14 mm nut.
then just repeat the process for the rest of the valves.  so next you will bring the 2nd valve fully open.  at that point, the number 7 valve should be fully closed (2 + 7 = 9), so adjust it as you did the 8th.  and so on.
does that make sense?  did i get it right, the rest of you?
