I don't have a Ryobi as of yet but my Poulan convert, didnt seem to have a spark, so I checked the plug gap and it was about 30 thou. I reset it to 20 and then I set my coil gap to 10 to 12 thou. Then I got a spark when fliping by hand and after changing brand of plug I can almost hand start. It will pop but not quite take off. I only have to bump it with a starter.

You probably already know this, but it worked for me.
