Using this tool is quite simple. First, find the carburetor on your Briggs LO206. Then, use the adjustable slide to set the float height accurately according to your needs. To measure the float drop, just follow the normal process. When using it, make sure the tool is in good contact with the carburetor parts to get accurate readings. After use, clean the tool with a dry cloth and store it in a dry place to keep it in good condition.
