220 gpu balancing

I have a 220 gpu that has a automotive flexplte, the flexplte has a large balancing weight on it, I'm assuming the 220 is internally balanced and the weight should not be there? Any help would be appreciated thanks.

That flex plate is from a chevy 400 small block. Just remove it. I'm surprised it doesn't shake your rigging apart!!!!

I just got it to start after sitting 5 years, I have more work to do before I run it, I got the boat in traid, the guy I got it form put a rebuilt engine and ran it once but I'm sure it was shaking when he ran it.
