I did the exact same thing last fall at about the same mileage - never cleaned it prior. I couldn’t believe how much smoother it ran and the throttle response that it picked back up! It’s now on my routine maintenance rotation.

Glad you saw results. I didn’t at all.
Maintenance is not designed/supposed to always supply results. It is to "maintain". If let go long enough, a maintenance item will reveal negative results.
