wow thank you everyone for all of your help! I came off with simply hitting the middle part of the flywheel and popped right off! I also got the manual THanks buccaneer!
I have a follow up question, and this is my first time ever doing anything like this 
so I apologize if this is a dumb question! I’m having a bit of a hard time getting the grime/crud/rust off of all the parts safely especially the aluminum parts since I don’t want to ruin the aluminum and was wondering if you all had any good suggestions. Also if you have a favorite aluminum polish recommendations thank you!!
