    I think you can take the spring out to while setting the points. I don’t recall ever trying it but it might work.  As mentioned, a short tube held on by the flywheel nut will hold the cam in place.

    Something to watch out for, make sure the high point of the cam is centered between the two rubbing blocks on the points. Failure to do this can damage something as the flywheel is replaced.
