MODIFICATION TO WATFORD MAGNETOS FOR TIMING TESTS. WITH SPECIAL CAMS. X8796 X 5790 You will remember that some time ago we rearranged the standard Watford EO6 magneto with modified sleeve and special cams for timing tests. It now transpires that we wish to carry out these tests on the HO1 magneto, instead of the EO6, but we find that the sleeves are not quite interchangeable, and either we have to make a further modification to the EO6 sleeve which is already modified to be able to use this in the HO1, or to make a modification to an HO1 sleeve, and we should be pleased if you would look into this to see what is really necessary. If we use the EO6 sleeve on the HO1, we want to be sure that we are reproducing the same conditions as we should be xx with the HO1 sleeve. EFC. {E. Fowler Clarke - Electrical Engineer} | ||
