| X7690 30.5.29. Extract taken from Mr. Hancock's report of 2.5.29. X.7690. DISTRIBUTOR TO LOP.D.71648 LEC 2556 2560. X.8692. The tungsten contacts caused misfires after a milage of 5000 due to the points being burnt. The contact points had been incorrectly set in the first instance, full surface of contacts not being made. We have had similar settings without the points becoming burnt. We returned the contacts to Derby and received a reply see EFC/WD.{Mr Wood/Mr Whitehead}52 and EFC1/T11.4.29. | ||
