We have developed a blank jet that is easy to drill out to your specific requirements to tailor your jetting for your specific engine. The material used is soft enough to drill but will not dislodge or foul the fuel or carb.
Ideally you would use this jet with an Archimedes Drill and a set of Jet Drill Bits. You may also be interested in the Jet tool to guage the size also.
Once you have identified the exact jet size for your set up you will want to replace it with the correct sized one as these blanks will not last indefinitely.
