Ok assuming I have the right TDC on the compression stroke. I tightend each rocker nut until I felt drag on the pushrod then tightend another half a turn. I am thinking this is what mark is talking about. However Billa once I tightend the extra half turn I could not turn the pushrod anymore. Should I loosen it up again so the pushrod turns? Then when I rotated the engine 360 to finish the rest of the valves the pushrods on #1 cylinder can turn again. Now I am confused?
