OS 60 FSR or 60SR Engine what is the differance in them
I pick up anOS 60FSR engine about a month ago, the person i bought it from said it's a 60 FSR engine,but on the crankcase it's says 60SR whats isthe differance in these 2 engines.Does anyone know where i can get the maunal forthisengineif i need parts for it because i go to the OSwebsite and they dont even have it listed. I dont know how old this engine is.This engine looks very clean and the guy told me it runs pretty good. I like to make sure that i did not throw money down the drain because i dont know much about OSengine , A freind of mine told me they are pretty good only know the guy for a couple months.I also found the muffler that goes with this engine OS #744 muffler does anyone knows where i can get the gasket for it or can i run this engine with out the muffler gasket or can i make it. i am looking for the screws to hold the muffler in place as well dont know what size it calls for it.
Any help i can get will greatly apprecate thanks.

There is no difference between an O.S. Max .61 FSR and an engine that says "SR" on the side, had a front carburetor and has a .61 displacement.
The "F" in "FSR" means front-mounted carburetor. If it had a rear-mounted carb, you's have an O.S. Max .61 RSR engine. The crankcase, cylinder liner, piston, ring, and rod are identical. The "SR" means it's a Schneurle-ported engine.
