Hi, my name is***** will be assisting you.
Which engine do you have on this machine?
You will want to remove the valve cover(s) to access the rocker arms and adjustment nuts. Once you have access to the adjustment nuts, there is a set screw in the center of the nut that will have to be loosened in order to make the adjustment, this screw normally has a torx head.
You will want to set all valves at .004 inches with the engine cold. Be sure that you tighten the set screw back down once the adjustment has been made.
Normally I like to set the valves by turning the engine until one valve it fully open set the opposite valve, then turn the engine until the valve that you just set is fully open and set the other one. This takes any and all chances or mistakes out of the equation. Otherwise you have to be concerned about the compression release and finding tdc.
No there are no torque specs for either of those.
