O.S. Engines 3A200 GGT15 Gasoline with E4040 Muffler

Mar 11, 2020

Same mounting as OS FS 91. More power, not to mention no more high priced Nitro.

Same mounting as OS FS 91. More power, not to mention no more high priced Nitro. Can't go wrong with OS engines. This engine went on a Mojo 60. Maintain oil ratio recommended by OS. Run it rich for a couple tanks at a little less than half throttle to blow and wash out any crap. Now lean it up still using the break in oil and fly. After a while, go to OS recommended oil mixture and retune. I run Klotz oil in all my gas engines and no problems
