I did have run-on all the time with my 427BB, no matter what I did. I had a Holley 850CFM mechanical pump four barrel and did everything you can think of and never got rid of run-on.
I have Webers now and do not know what run-on is. Maybe it has something to do with the carburetor, because everything else is unchanged.
But I think that it could have to do with the advance of the ignition, because with the Webers I did have to advance ignition to 18º. I never did that when I had the Holleys on, and maybe doing that could help. Retarded ignition will heat up engine more and that could cause run-on.
