For a green hand setting valve lash (rocker arm to valve stem clearance) find the TDC line on your timing on the compression stroke. (both rocker arms on number one cylinder all the way up)which means both push rods are all the way down. Take a 5/8" box end wrench and loosen a lock nut. Leaving the wrench on the lock nut take a screw driver and adjust the clearance to a snug sliding fit on a .012 feeler gage and holding the screw driver so it will not turn, tighten the lock nut. Move to the second rocker arm and do the same. Next do the number two cylinder by turning the engine just enough to have both rocker arms all the way up as it was on number one. Then following the firing order do the same on number four cylinder. then move to number three. Doing it this way you follow the firing order of 1-2-4-3. This also helps under what is happening to make an engine run. By understanding how the valves work you can then take any engine and find the firing order by removing the valve cover or covers and turning the engine by hand and mark each cylinder as both rockers are both up after finding the compression stroke on number one.
I am a big believer in the many details of the running engine learned when working on them rather than just assembling them and hopping for the best. In my opinion it makes it more fun.

Today's Featured Article - Talk of the Town: Winterizing Engines - To Drain or Not to Drain? - by Russ Berry. What is this strange attraction I have to equipment and machinery? How did I get this way? I came from the suburbs and own a small horse farm in rural Loudoun County, Virginia. You can call me a "weekend farmer." The local farmers do. Does it bother me? No. I am just happy to have their friendship. At least the word "farmer" is in my title. But what is the attraction? How can I explain the sensation and exhilaration I feel when I turn the key and hear the engine come to life (most
