Anyone know anything about these?
I bought a IH LB engine and don't know a lot about it. Runs well but doesn't seem to be getting enough oil to the valve rocker assembly. I noticed what looks like an adjustment screw and locking nut on the end of a small pipe. Also one on the rocker shaft assembly. I think the one on the end of the tube is the oil flow adjustment. Confused about the one on the rocker assembly. Does that one just lock the rocker arm shaft in place or is it an oil flow adjustment also?
