two stroke repair

[sauce]

So, I like to think I'm a pretty handy guy. I can take care of most repairs and maintenance my equipment. Recently my manual start 20hp 2 stroke has been giving me some ignition grief. Simply put, no spark. I took it in last summer and was told that the stator plate needed to be replaced. So I replaced it $$$! It ran fine till one trip this spring. Now it won't start. I've been procrastinating and now feel that it must be fixed. Id like to know if there's a way to diagnose the source of the problem. I think it comes down to moisture/ wear and tear. Its possible that the stator is toast again. But it could also be the coils or the control box. How can I tell? I know there is a way to test every component of the ignition system using a multi meter. But I don't know where to begin. Thanks for any suggestions. And big thanks if you point out an easy fix

First step is to get the shop manual for your specific motor, it should have the schematics of the wiring and values and how to do the diagnostic with a VOM, save you money with replacing only the required parts.
