Works great, a good way to troubleshoot carburettor and ignition problems, you can se the color inside the sylinder, and then adjust the carburettor so the color is blue, if you are on the richer side, the color will be orange, and if you are on the leaner side, the color will turn purple/white

My main reason to order this tool was to be able to adjust the idle circuit on carbureted motorcycles. The tool is easy to use and the change in color is easy to identify to adjust air/fuel mixture screw. I have used it on a couple motorcycle already and the results have been better than expected. Just realize that this tool only helps set the idle circuit and adjust how lean or rich you wish to run a motor.

works very well and makes the colour tune much more useful the copper washer is too big for the thread and tends to fall off easily but the quality of the colourtune itself is excellent
