Well I fixed the rattle scrape.
I was poking around while the car was idling and I narrowed it down to around the carb. I looked under the carb and noticed that a pipe for the emissions that once had a plastic cap, no longer does. I placed my thumb over it, the rattling stopped. I removed my thumb and it came back. I placed my thumb back on it, and pulled on the throttle a bit and got no rattle/scrape like I was.
Looks like I just blew the cap off while driving.
Now I dont know what exactly was rattling, but I at least fixed it.
