The removal of the carburetor jet can be a real challenge. Too much force with the wrong tool can distort the main jet causing it to be permanently fixed in place, ruining the carburetor.  Our handy tool threads into the inside base of the carburetor jet and grips it firmly.  Now the tiny hammer can be used to knock the jet loose, saving the carburetor.  The right tool for the job is always much more productive and provides the greatest cost savings.
