Question:
I have a new HU675AWD walk behind mower. It is 3 months old and has less than 20 hours on it. It starts on the first pull but will not stay running. It dies immediately. It acts like it is not getting fuel but the line is clear, and has fresh fuel. This is the first time this has happened. Any ideas anyone? Has anyone else had this problem?
