Looking for someone that can give me the replacement order info for Briggs and Stratton 16.5 Intek that was used in the 2010 Husqvarna RZ 4216 mower. I no longer have the original motor and to order a replacement I would need shaft size and length etc. If a member has the same machine the motor replacement info can be obtained from Briggs and Stratton website by submitting the engine model and ser # that is on stamped on the valve cover. Appreciate anyone that can help.
