Cliff Ruggles:
The later castings also used a divider between the float bowl and the accl pump well. 

I suspect most the fuel that chases the pump shaft comes from spray the needle/seat area and some splash from the float bowl. 

I use a 1977 carburetor with the divider in place and don't have this problem.  I also peened the material around the pump shaft down some, then drove an old pump thru the smaller hole to create a tighter fit.

I don't stock the seal and retainer for the late model carburetors that used them....Cliff

motorvation2go:
Thanks for the reply Cliff
Good of you to be ever helpful.
Seems the seals are no longer available anywhere... at least within the limits of my present search.
I have full access to a vertical mill, lathe etc... was considering making a close tolerance bronze (press in) bushing.
However, your idea for peening the existing hole sounds like a better approach.
Simpler is always better!
Will keep looking for (or perhaps rigging) an appropriate seal.
Incidentally [my] carb experiences the fuel wetting problem even with the vertical well baffle in place.
Thanks again.
