NIBBI Carburetor Idle Surging? Here’s a step‑by‑step tuning guide that actually works. 🔧

We’ve seen many riders struggle with unstable idle after swapping to a NIBBI carb – revs jumping up and down, no consistency. In this 3‑minute video, I walk you through the 3 most common culprits:

1️⃣ Intake air leaks (the hissing sound)
2️⃣ Idle speed screw adjustment (target RPM)
3️⃣ Air/fuel mixture screw tuning (find the highest stable idle)

No special tools required – just your ears and a screwdriver. Watch till the end, and if you still have issues, I cover what to check next (fuel, filter, spark plug, pilot jet).
