| Craig - I hooked up a vacuum guage to see when the step up springs were coming in - that let me judge if they were the issue or not. Not, in my case.
My advice would be to get a vacuum gauge , and go out and see what the guage is doing when you get your flat spot - you can easily see if the rods will be up or down at that precise time if you do that.
What kind of rpm/throttle opening does your flat spot occur at?
