## 🛠️ Service Notes

-   Note and record the existing setting before disturbing anything, so you have a reference to return to if needed
-   Release the lock nut fully before turning the screw, then reset the lock nut and re-check the setting — tightening the lock nut usually moves the adjustment
-   Set to the clearance or position given in the workshop manual for your engine using the correct feeler or gauge; do not judge the setting by feel
-   Inspect the tip and the threads and renew any screw with a worn, mushroomed or picked-up tip, because a worn tip makes the setting drift in service
-   Never use an adjusting screw to force a component into position, and carry out a hot re-check after running if the manual for your engine calls for one
