OS 61 FSR-ABC
15% nitro 11x7 APC stock muffler 12700rpm(seal level) Same fuel, same prop, modified stock muffler 13300
any one else still use these engines?
This a very well run, past its prime OS engine..I won it on ebay ... Upon changing the bearings i noticed the sleeve has some deep grooves in it, i can actually see the brass in the sleeve. but seems to run well on the bench...my goal is to pipe it one of these days.

hi if you are looking at the brass in the lineryou have worn through the chromeit is time for a new piston and liner- once that starts it is a self distruction modethe liner will sand paper itself to death in a short timedo not put this engine on a pipe until you replace the liner the problem is you can buy a new engine for the cost of a piston and liner parts would be hard to find for that engine -i would return the engine to the person who sold it to you if you still canas you bought a very used up enginei have done this many times when i paid with paypal as they stand behind the sale-you can even ask the seller to pay return shipping if he misrepresented the itemGOOD LUCKENJOY REGARDS TONY

I had one in the 90's. I milled the exhaust port for 170 degree duration, then it would turn an 11-7 APC an honest 15,000/15% nitro. Enjoy yours, I wish that I still had mine.
