The tests given in the attached report were taken in connection with the 110° Camshaft which we have found to be an improvement on the EAC-1 and 20 HP. engines.

On the 40/50 HP. we have not obtained the same percentage increase with this Camshaft as we have on the other engines although it does give approximately 5% increase.

Further reports of tests will be sent in connection with this.
