Get some acetone on a rag and do more cleaning on the flywheel.
ive found the simplest to do this is to remove flywheel dust cover to expose the bottom of the flywheel. clean/rotate, clean/rotate until you go all the way around. you'll see the mark. what i do after that is to paint the
U/C white and polish the ball up nice and shiney. might as well, that way some time down the road when you revisit this (and you will) it will be still easy to see and find.
