OS Max 40SFR muffler problem
Help needed with my OS Max 40SFR engine muffler mount area problem. I can't use the standard OS743 muffler as I broke a chunk off the left mounting hole so I need a bracket style muffler and there isn't any. A OS703 bracket style muffler from a OS Max-H 40R/C engine is too wide to fit the 40SFR mount. Hope someone has a solution.
