We understand the Test Dept: are setting the eccentric motion levers slightly different to that shown on our arrangement drawing E.72652 Sheet 1, which is based on LeC.1919. The modification consists of setting the lever pivoted on the inclined shaft about 10° towards the crankcase, as shown in sketch below, which results in a reduction of the magneto control range. Please let us know as soon as possible if you agree to this. yes AS SHOWN ON ARRGT DRAWING E72652 54° 40° 90° 10° 90° MODIFICATION. By/SS.{S. Smith} BY/SS.{S. Smith} | ||
