Barry Grant/Holley 750 Double Pumper Base Plate Question

So,the real question: What's wrong ,with the current base plate ?.
The current base plate is leaking fuel , between the shaft and the lever.
Every time I move the blades, a few drips of fuel are leaking and wetting the Edelbrock air gap manifold..... and I don't like free fuel on hot surfaces :rolleyes:
After a few minutes of driving, it's getting ugly and after half an hour I have a litle sea of fuel under the carb on the manifold......

BTW, I know the BG story and a few month ago I had contact with him, but that wasn't realy helpfull....
