4. GENERAL DESCRIPTION OF ENGINE COMPONENTS /" ROBIN EH63V/ 65V series engine is air-cooled, 4-stroke, twin-cylinder, OHV arrangement gasoline en- gine. The twin-cylinder is located in the angle of 90 degree; #I cylinder is in the RH side and #2 cylinder in LH side as viewed from flywheel (cooling fan) side.
4-4 CONNECTING ROD AND PISTON The connecting rod is forged aluminum alloy, and its large and small ends function as bearings. The piston is an aluminum alloy casting, and car- ries two compression rings and one oil ring. Fig. 4-4 4-5 PISTON RINGS The piston rings are made of special cast iron.
4-7 CYLINDER HEAD The cylinder head is an aluminum die-casting which utilizes semi-spherical type combustion chamber for the high combustion efficiency. 4-8 VALVE ARRANGEMENT The intake valve is located on flywheel side of the cylinder head. The cooling fins and passages design lead cool- ing air to the exhaust valve area for the optimum cooling.
4-10 COOLING SYSTEM The large fins on the flywheel provide sufficient cooling air capacity for cylinder and cylinder head. The cylinder baffle helps the cooling air flow effi- ciently. 4-11 LUBRICATION SYSTEM The engine is furnished with full pressure lubrica- tion system.
4-14 CARBURETOR The engine is equipped with a horizontal draft car- buretor that has a float controlled fuel system and a fixed main jet. The carburetors are calibrated carefully for sure starting, good acceleration, less fuel consumption and sufficient output.

6. MAGNETO 6-1 OPERATION AND FUNCTION The ignition system is a pointless flywheel magneto with automatic advancing characteristic. Being different from the breaker point type ignition system, this system is completely free from such troubles as starting-up failure due to dirty, burnt or corroded point surface.
(2) At lower engine revolution, when the flywheel reached the ignition point the low speed ignition timing control circuit operates to run the base current 13 to turn the signal transistor A "ON" allowing the current I1 to bypass as current 14.
