After reading that it will not pop even though you have what looks like good spark try reducing your plug gap down to .025 or even .020. We just did that on an opposed twin a couple weeks ago and it responded pretty well to that change.
If and when you do get it going I would get some genuine OMC Engine Tuner and run it through it. About 1/3 of a can at a time and let it sit overnight with each application. Much more effective than SeaFoam at de-carboning piston rings. It’s the real deal.
