Sounds like an accelerator pump issue. Last time I did a rebuild I noticed that the replacement cup as I call it didn't have a spring that went inside it like ones I had seen before. If its bogging right off idle that seems suspect to me as its not pushing fuel through the carb. Operating the throttle can make the plunger roll in the bore causing intermittent problems or if you put it in upside down. Did you see if your getting a good strong squirt of gas with the engine off when you checked the secondaries?
