My engine sounds chunky and loud

[littlemac]

A couple of summers ago, my kick start, starter and return spring got all jumbled inside the case while I riding it. It sound like some rocks got in there, it made some loud sounds, then quit running.
I have everything put back together; put in a new starter I had just in case, and now it starts right up again. However, it sounds pretty bad now. It makes loud chunking sounds, like gravel in the engine, so I am not riding it. Any ideas on what to look for?
It did not make this sound before the spring jammed.

Junk in the clutch?
