My next crazy project.

Yea I think I will start with the slinger and run it and see what happens im gonna enlarge the oil holes to the head and see if im getting enough oil to the rockers if not ill go from there better to start simple and then trouble shoot. I'll make my own slinger out of some sheet metal I have plenty of scrap from the rusty ram project. Lol

No rockers on that lawn mower engine, it's a flat head.

The valves sit down in the block deck. So the oil sliger will sling up enough oil just fine to lube the valve guides just above the cam.
