took my engine apart thinking i could fix a problem that wasnt really there. few months later engine is back in and the atv (pentora 250cc manual) is running but revving really high at idle. adjusted carb nothing, shifted gears nothing just revving high. after some back and forth it sparked somewhere in the front area and now i get nothing. Nothing. Just the rear brake light works. i havent been able to find any info on engine parts or diagrams. hoping We can figure this out
