In addition to a high fuel level or incorrect float settings or leaking needle and seat, of course higher than desired fuel pressure from an electric pump could contribute to the problem. Another concern is that overtightening of the cover plate screws will ultimate lead to warpage of the castings and when that occurs the gasket may be unable to provide a seal even against the random surging of fuel due to road motion. Really good rebuilders will check the flatness of the castings and correct them when possible.

After perhaps 10 years and 10,000 miles the exterior of my dual Rochesters are still nearly as pristine as when they were installed. They were rebuilt by Daytona Parts.
