Remove the rocker covers, remove the spark plugs, rotate engine clockwise by hand with your finger over the spark plug hole till you fell compression building, then with a piece of wire or other tool, bring the piston to the very top of cylinder, this is TDC, then make a mark on your tool and turn the piston in the same direction till it goes down 1/4 in. .0250. Set both valves at .006in. , repeat on second cylinder. Thanks.
