To: E.Y.B Order No. W.A 89 Customer's No. X 430 Standardised Gap & chemical leak test on Various magnetos For the purpose of tentatively completing our specification of magneto performance, a number of magnetos have been tested on our standard gap and chemical leak. (3.0 m.m annular gap and 3.0 microhms leak). The speed limits between which the magneto sparked regularly were observed to be as follows:- Signed: contd.
