That is somewhat normal. The only thing I would check is your low end, 4 strokes have a much higher tolerance on the needles when compared to a two stroke. I have seen four strokes with the low end 3 turns out of tune…it idled rough but it didn’t die. I would just make sure your low end isn’t too rich (start the engine, go to full throttle, tune, drop to idle…..let it sit for 30 seconds…..then gun it to full throttle….if it stumbles/hesitates lean it out, if it sounds like it is about to die richen it up.
Don’t think too hard…..try one way….if it doesn’t work….go the other way
Personally if it is running reliably don’t stress it, just fly it, if you like to tinker with engines (who doesn’t) then verify the low end is tuned

Good luck!
