WB Carburetor Adjustment Tool

This tool takes the guess work out of adjusting your WB carburetor low screw. Easily adjust with ultra fine precision using either sight markings or physical stops. Easily return to a previous setting or share your setting with others.

• Magnetic tip makes engaging the tool easy and retains it when you let go*.
• Multi material construction provides strength where it matters while retaining economy.
• 1 minute increment adjustments via sight markings or physical stops.
• No more fumbling with a screwdriver or getting burned by the exhaust.

If the head of your low needle has been damaged by ill fitting screwdrivers, this tool probably will not fit any longer. Do not force it. Please check if yours is damaged before ordering and consider purchasing a new low needle with the tool. The tool WILL NOT fit on the damaged needle pictured in the gallery. This is because there is a near zero clearance interface for precision. It would be pointless to have 1 minute markings if there was 3 minutes of axial slop like a regular screwdriver.

Sales spiel:

You wont get precision with a screwdriver. Did you open it 1/4 turn like you intended? Most likely not. Now you know you opened exactly 15/60ths of a turn. You Don't have to crane your neck to see that either.

Adjusting up to your hesitation point to find your optimum setting? You're no longer making an inconsistent change, move up in 1/60th increments and once you hit it richen it exactly how much you need.

Want to get rid of that mid range bump, improve starting, or think an issue may be related to tuning but afraid you might make things worse? Not a problem with this tool. Record your position precisely before you start a tuning session and if all else fails just put it back exactly where it was.

Manufacturers and frame retailers, send one to your customer and be certain they are executing your directions correctly instead of an endless loop of phone support.

*Please remove the tool when running the engine.
