We have noted that the glands of the throttle system will require to be a high class job as considerable external leaks occur.

GENERAL CONCLUSIONS.

It is proposed to carry out some flight tests on the carburetter on the Tollerton 'Hart' using a hand control for the mixture in order to obtain the calibration for determination of the altitude needle. At the same time the S.U. Company will carry out blower rig tests with the object of producing a flat metering curve. For this purpose we are providing a separate attachment carrying the throttles for attachment to their blower rig.
