| Typed Text: COPY. X.4387B - PILOT JET TO REPLACE PRIMER. We attach copy of standardisation sheet in connection with the above experiment. Will you kindly remark upon, sign and return at your earliest convenience. We have now had consider-able experience with the Pilot Jet. About 12 sets have been fitted to different cars. All of them have been successful. We have heard from Springfield that the Pilot Jet has effectively overcome all their starting troubles.
