Timing on a kfx 50

if it broke the timing chain it might've bent the valve

you can prob pick up a new key switch on ebay for 10-15 dollars

green is top ring, the spring goes under the oil ring the top ring has slight angle towards the inside.. (not square) the angled edge goes up!!

you should probably find a manual. the springy one is an oil ring.

there should be a hole in your flywheel that line up with the screws and your coil loosen it up and you slide it back and forth hard to get it so far out that it wont start though if possible it would be easier for you to pull the flywheel then you can adjust it by hand starting the center and see how it does

find a good local machine shop and they can repair it so it works correctly

could be faulty plug

sounds like the reverse override switch wire has come unplugged. check the wiring.
