Alright fellows I need a little professional help here. I just rebuilt the top end on my sx viper, changed the jet needle to the 4th clip top down, both washers underneath the clip, carbs are spotless clean, air/fuel screws are turned out 2 turns, when I snap the throttle I’m getting some bog, I did the carb cleaner air leak detection method, found nothing, could an exhaust manifold cause this issue or bad power valves, thanks in advance, Jeremy
