Non-OEM Precision Tuning Tool
A non-OEM specialised 2-Stroke Carburettor Adjustment Tool, designed to adjust fuel-air mixture screws on high-street garden machinery, strimmers, brushcutters, chainsaws, and multi-tools (including selected TTL488GDO and TTL530GBC models).
Fine-tune engine idle and high-speed mixture settings on 2-stroke small engines with this ergonomic adjustment tool. Because small engine manufacturers fitted multiple carburettor brands (such as Walbro, Zama, Ruixing, and Huayi) across different production years, screw head profiles vary from machine to machine. We stock fourteen distinct tip profiles - ranging from Pac-Man and Splined to Single D and A-Circle - ensuring you can select the exact tool end required for your carburettor.
Titan Pro Tech Tip: How to Select the Correct Tool Profile
Please inspect your carburettor before ordering! Machine model numbers alone do not guarantee a specific screw profile, as manufacturers altered carburettor designs across production runs.
1. Look closely at the High (H) and Low (L) mixture adjustment screws on your carburettor.
2. Match the head shape and diameter against the profile diagram photos shown on this listing.
3. Select the matching profile name (e.g., Pac-Man, Single D, 21-Teeth Splined, Acircle) from the dropdown menu above before adding to your basket.
Constructed with durable steel shafts and molded ergonomic handles, these precision tools allow incremental 1/8th-turn adjustments without slipping or damaging anti-tamper screw heads.
