Predator 212 bogging/running rich

Just fixed mine idled but wouldn't rev.
Remove valve cover. Locknut for intake valve rocker worked loose. With cover on, it was enough to push the spring edge and open the valve. Once cover was off, rocker flopped free. Reuse gasket if your gentle, and set with feeler gauge.

What color is the spark? It must be white. If yellow the plug, coil gap, or coil itself/high tension cable are at fault.
What is the coil gap?
How is the key on the flywheel?
What is the compression of the engine?
Did you pry out and clean the black plastic idle jet? It is open to the world and can clog easily. If clean how is the tiny "O"-ring on the jet?
If cut,torn,rotten the engine will not run properly.
