Good Morning All Last week I posted new to the forum and got great response on my C-100,,,,,, now running. I also have a 516H,,,,,, or my father-in-law does. At the end of last year it quit and he tried to fix with no success. This weekend I re-assembled what he had apart. The engine turns over but after tinkering a bit can see that it has no spark. I would appreciate it someone might give me a list of test/checks that I might do to help pin point the problem, similar to what people did for my C-100 post. I don't have a problem following an individuals lead but I do not have the knowledge or understanding of these systems to develop a diagnostic process. As before,,,,,,,,,, thanks in advance for any guidance. Regards c
