Lately when advancing the throttle for takeoff, passing the 2000-2100 rpm range the engine seems to stumble/"bog down" for a couple of seconds as the throttle is still being pushed forward. Then, the engine bursts on up to full power. Runs smooth from then on. In flight, no hesitation at all if going from idle to full power, even if simulating a go-around starting from approach speed/full flaps.
Also I've noticed the pre-takeoff mag checks seem a little rough, almost like the engine is "missing" a bit. Leaning during the mag checks seems to smooth things out to a normal single-mag sound/feel.
Not sure what the cause is. It's almost like the engine is too rich when at full-rich mixture. I do lean aggressively on the ground after start-up. The engine is a Lycoming IO-360-B1B, Whirlwind constant speed prop. Slick mags, harness, plugs all new as of Aug 2021.
