It could just be because the engine comes in hotter after a run, and not necessary that it’s not tuned right. You would just have to give it little bit of throttle before runs in that case, if you turn idling speed down to right when it’s hot. Engines can be finicky at times; particularly high power engines, and two engines that are the same can act differently at times.
