Os Older 25 Not Fp25 - Need Muffler
I HAVE A OLDER OS 25, NOT THE FP SERIES THAT I NEED TO FIND A SOURCE FOR THE CORRECT MUFFLER. IT EXHAUST PORT LOOKS LIKE IT HAD A SCREW IN THE MIDDLE TO HOLD A MUFFLER ON. CAN ANYONE TELL ME WHERE TO GET A MUFFLER FOR THIS ENGINE. THANKS

Ghost,
Your engine's old enough that there would be no O.S. parts for it from us or O.S. It sounds like the old crossflow O.S. Max .25 R/C. You may need one of the old strap-on mufflers.
If your engine's the old .25 R/C, youll need an O.S. Max #702P muffler.
The hole in the web in the center of the exhaust stack on the engine is for the exhaust baffle that was used to help unmuffled engines idle. The increased back pressure at low RPM kept the glowplug warm. Muffler use replaced the need for a baffle.
