F20B homework
 

i have an F20B motor and i've been reading a lot of the threads on this motor in the archives. i know there is not a lot of info out there on this motor and thought it would be helpful to show all the info i got. the majority of the info is for the manual cause if you have this motor, it's the one you should have. if i made any mistakes, feel free to make any corrections.
