X8040 Sales have asked that they can try an EAC.11. car fitted with low compression pistons and any other modifications which it is proposed to incorporate on the EAC.11. chassis. We have therefore started to prepare 93-NK which is the covered car fitted with an EAC. engine which we brought to W.W. last week. The following new parts are being fitted to this car :- 1. New engine unit. This will have low compression pistons, Low lift Camshaft and Governor for throttle. 2. EAC.11. Gearbox. This is a 40/50 HP. gearbox with sliding change speed lever and new brake lever. 3. Engine Coupling. This coupling will have the fabric joint larger in dia. than the one previously fitted, taking advantage of the fact that the starter motor will be on the engine. 4. New EAC. steering, slow type with new steering wheel and controls. 5. Control to front axle. 6. Complete set of EAC.11. electrical units. The wiring and arrangement of the units will have to be temporary as it will only be a standard 40/50 HP. dashboard and bonnet. We propose, on this car, to retain the Scintilla Magneto with the automatic advance as we shall not have ready in time the R-R relay scheme. contd :- | ||
