| - 3 - LeC.3114 shows open type head with improved water cooling of sparking plug boss, the latter being obtained by modifying the induction system as shown. We should prefer, however the section through the head, illustrated on LeC.3115 if all the other features can be made satisfactory. E.{Mr Elliott - Chief Engineer} | ||
