That was my discovery when I tried it a few years back, Jim.
There are a number of known solutions to this problem.
At the moment, and for the last couple of years, it is fine
(insignificant vibration at most RPM), due to appropriately placed penny
washers, at the three potential attachment points near the base of the
prop blades.
Many have used professional balancing. I used trial and error on several
flights.
However, an important preparation was to ensure the spinner cone itself
was within tolerable limits from the point of view of shape and weight
distribution. Some rubbing down was involved.
I'm sure much advice will be forthcoming on this.

Subject: spinner
Hi gents, I am new here. I have a classic Europa with about 160hrs. It
has always had some vibration so After talking with Jim Thursby I flew
it with the spinner removed. It is then the smoothest plane I have ever
been in. I think my problem was and is that the spinner wobbled because
it is not exactly straight. My problem, how the heck does one get it on
straight?. I have tried many times to no avail. Jim Stoveken
