Hey yaall.. I have a Robin EC04er 40cc engine.. I would like to put on a muffler like what is in the 2stroke kits. ( the short pipe out of the engine, then the canister). THe bolt holes are 38mm apart center to center on the engine.. Do you know if any of the kit mufflers would fit.. Spooky Tooth said his would not.. Thanks Bill
