Perhaps it was only flat tops that were deficient in enricher holes.
So Bing knew how to engineer a progressive enricher in 75. I can't fathom why they went backwards in sophistication bewtween 75 and 79 and then needed a service bulletin to put it right.
Have you noticed yet? That a lot of what goes on with building and tuning and making these things go is what is called "Bench Racing"? Most of us build everything in our minds before we build it for real. Sometimes this produces problems and the process starts over again.
The Pros, Bings engineers, do the same thing. They make it work and modify it in their minds then build it for real. The only difference between them and us is that they get paid to do this.
