1) I have a Mecoa muffler on a YS61 side exhuast,
www.mecoa.com, part number 930-61. I believe it is an OS61FSR muffler. The holes need to be elongated a couple of thousandths of an inch to match the YS holes.
2)Certainly equal.
3)It is easy. Is there such a thing as hassle free? It uses a pressurized fuel system versus a muffler pressured system.
You won't get anything for the engine on eBay, nobody likes these engines. Could I send you my address and I will take it off your hands?
