If you own and work on small engines, you should have one of these tools laying in your toolbox. To me, this is a must have item if you work on small engines.I have cleaned so many carburetors over the years with these tools and I ended up purchasing a second one to have as a back up. These days, the majority of carburetors that need cleaning can be fixed by simply running this tool up into the jet of the carburetor which fixes most problems.
