we have a older cub with the ch15s kohler. it would back fire once in a while but restart. now it has good spark and fuel but wont start, pulled the engine out checked and flywheel put a new shear key that didnt shear the old one. dont know what else to check? any help would be wonderful. thank you rick farnell
