Its getting fuel...nice blue spark..and it has plenty compresion when kicking it over
There is no way to tell how good your compression is by kicking it over
Your auto decompression at kicking speed reduces comression to 50ftlbs so it will start easily
Once running it's up near 140ftlbs
Have you pulled the float bowl yet to see if there is debris in the pilot?

First sign of hard starting usually means the valves need adjustment....BUT since you said it died suddenly I would take out the little center cap on the left case and see if the bolt that holds the flywheel tight is loose. It is a simple quick check and has been known to happen before. The factory even sent out a bunch in '03 that all did this.Mine even did it a few years later.
What year is it?
