http://www.oldgravelys.net/pdf/Conv_10_10A_12_Serv_Man_0675.pdf See starting at about page 32, no real step by step but the pics are self explanatory as to where/how the adjustment is made once you get to the right page and compare it to your engine. Basically the engine must be cold and at TDC on the firing stroke so that the valves are fully closed. IMO it is better to be a little on the loose side rather than tight. And use a little Marvel for lubrication. I use StaBil year 'round in all gas and there is StaBil for ethanol if you have ethanol in your gas. Jim
