Why can't you move the piston to the compression stroke (so both valves
are closed), tighten up the pushrods so there's no lash and be done? I
thought this would be super simple.
Or put the piston at TDC firing, which is simplest, and then adjust.
However, I don't like to fiddle with 2 small wrenches at the back of the
rocker arm on the backside of the head. If that's not a problem...
That's why I much prefer adjustable rocker arms. Simple, swift, and sure,
with the adjustment right in the center on the rocker stud, where it's
easily accessible.
