OS .61 FS Fuel Pump??
Need some advice in plumbing an OS .61 FS with a fuel pump. On the pump assembly at the back of the engine there are 4 nipples. The two top ones say In and Out. The two bottom ones say S and R. I have no manual for the engine and have never seen an assembly like this. Any hints/knowledge with regard to hooking up the fuel supply would be much appreciated. I would also like to hear about engine performance, is the fuel pump worth having?
Thanks again for your help!

RE: OS .61 FS Fuel Pump??
Inlet is from the tank pickup clunk, Outlet goes to the top fitting on the carb, S goes to the lower carb fitting (boost pressure they call it), and R goes back to the tank as an excess fuel return. Don't use exhaust pressure on the tank.
It is a stronger engine and will swing slightly more prop than the stock 61SF from my experience. It also eats more fuel. Good luck.
