Maybe someone can help me here. I inherited a small ME109 that came with a .15 engine. The only markings on the engine are .15 on the side of the block and MRC on the carb. I did a search for MRC and didn't really come up with anything. Anyways, the engine came with no muffler, and I was trying to identify it so maybe I could find one to fit it. I'll post a pic from home this afternoon. Was there an MRC that made engines? I know back in the `70's everyone and their brother had their own design. For some reason, when I look at it, it I keep thinking Enya ... but then again, if I were THAT smart, I wouldn't be on here looking for help
