TWIN CHOKE CARBURETTERS ON 20 HP.

Y5080
Y1053

After the success of the Solex carburetter on Phantom ll we are anxious to try the effect of a twin choke carburetter on the 20 HP.

For this purpose we have obtained a twin choke Zenith carburetter and should be pleased if you could supply the drawings and the necessary instructions for an induction pipe to suit this carburetter for fitting on a 'Japan' engine.

We could supply the carburetter as a model if required.

Print of the type of pipe we require is appended.
