Benefits & Tips

• Speed up tuning: Quick, secure engagement with the 21-teeth splined interface makes carburetor adjustments faster, especially when working across multiple models.
• Protect your screws: Precise grip minimizes cam-out and stripping on delicate adjustment screws common in two-cycle engines.
• Pro tips: Before use, verify compatibility with your carburetor model. Align the splined circle with the adjustment screw and apply steady, light pressure to avoid over-tightening.
