FLY WHEEL

i have a 75 150 super vbc1t and i'm trying to get the flywheel off, i got the bolt and the retainer ring thing off, but i'm having trouble gettin the flywheel off, can you use a puller? on that braces on to the crank bolt and pulls the fkywheel or does the flywheel twist off? lemme know thanks
I just tried putting in a new circlip and still cant pull of the flywheel
