HOW DO WE FIND OUT HOW TO FIX THIS MODEL

Answer
Please turn off your caps lock.  All upper case letters make it difficult to read.  As far as finding out how to fix it that is too broad of a question.  If you are looking for a service manual you should be able to get one through Briggs & Stratton or one of the many dealers online.  You can also try your public library for service manuals.
