2023 Jeep Wrangler Rubicon — carbureted engine stumbles only when I tip into throttle

ColdStartNerd7Community StarterNov 11, 20252023 Jeep Wrangler RubiconNYC / Long Island

2023 Jeep Wrangler Rubicon, about 96,000 miles. Idle is decent and it cruises okay, but a quick throttle input makes it stumble. I'm trying not to change three things at once. Accelerator pump, timing, vacuum leak—which test would you do first? If I fix it I'll come back and update the thread.

This is usually cheaper to test than to guess. Two 2023 Jeep Wranglers can feel identical and have different causes, so measure before you copy someone else's repair. If the cheap test changes it, stop and reassess. Was this after sitting overnight? If it repeats twice more I'll book time.
