QuestionOK, one more! What are the torque specs on the bolts on the inside of the valve cover (but not the 1 head gasket bolt). I am somewhat new to this but it seems simple enough. I would like to explain how I think it is supposed to work and have you tell me if I am right or way off track. I have taken everything apart to fix a sticky valve and now I need to put it back together. There are 2 push rods that come out and touch a sort of rocker arm looking thing. In the middle of this rocker arm is a bolt and the other side of the rocker arm pushes the valve that has a big spring on it. I am pretty sure how this goes together but the bolt is confusing. Half-way through the bolt is a nut. It seems to me that you thread the bolt until it touches the valve (which is top dead center) and then you tighten the nut to keep it in place. Does this seem right or am I way off. I appreciate your time and I hope you have a good day. Thank you!!!!

I have a 13 hp OHV Tecumseh engine on a Murray mower. What are the torque specs for the head bolts? The model # is OHV130.
Thank you very much!
Answer -
Hi Matt
They are as follows-
Cylinder Head Bolts - 230 in/lbs or 19 ft/lbs
Remember to start with the bolt inside the valve stem area, then work in a star pattern for at least two steps (tighten around to 8-14, then tighten around to finish.
Some people use a graphite compund if the bolts are going into aluminum no prob with that, just use a very tiny amount, and re-torque after engine reaches operating temperature.
AnswerHey Matt-
Sorry for the delay (vacation)
What your talking about is setting the valve lash. This nut isn't torqued onto the bolt, its tightened until the valve lash clearance is correct for that engine. I believe the valve lash is .010. You have a feeler gage?
