Fred, I should have said that the "slight roughness" that can be felt at an idle disappears at higher engine speeds...in other words, when sitting in the drivers seat and bringing the RPM's up, the engine smooths out but the tap can still be heard. You really wouldn't suspect anything was wrong when you punch it, it responds instantly with no hesitation but that tap, tap, tap and putt, putt, putt, doesn't belong in the recipe for a correctly running straight 8 or any other engine that's performing like it's supposed to.
