Default 120 4 stroke

Hi, I just bought a FS-120S-E 4 stroke, this is a brand new engine i have heard that you need to add a medium temp. grease to the rocker arms & springs, this is my first 4 stroke engine, my manual says nothing about doing that, with grease on therocker arms and springs wouldnt that obstruct the adjusting of the rocker arms, i was told to put in as much grease as i can. thank you Tim.

You don't need to add grease to the engine. The normal operation will get oil to the rocker arms. It gets forced up the pushrod tubes by the normal pumping action of the piston.
