I have an ignition fault on my Briggs and Stratton Intek
13.5 hp engine. It will not start. There is no spark at
the plug, but a neon tester in place of it does flash ok.
Tried a new plug.
Can someone please tell me where I can download a diagram of
the circuitry on the printed circuit board. A Google search
didn't help.

This neon tester flashes when the plug should fire, yes? Then the problem is
not that the plug is not getting any HT, but either the plug (new or not) is
faulty, or the problem lies elsewhere. Are you absolutely sure that the plug
isn't sparking, it can be difficult to see, especially in sunshine.

Something like 99% of mower non-starts are due to carb problems, usually
blocked carb or air filter, and that's what I suspect you've got.
