I'll look forward to hearing more, Andrew. If it isn't ignition or a fuel line blockage, the other potential causes are listed in that other thread. We're here to help in detail with investigating any of them. Incidentally Honda engines seem to me to have reliable ignition modules, but of course with advancing age, just about all mower engines are vulnerable to accumulated crud in the fuel system. Most of us find it when it causes a problem, but probably not before that.
