1. SPEC1 FICATIONS -1-.
2. PERFORMANCE 2-1 MAXIMUM OUTPUT The maximum output of an engine is such standard power as developed by that engine, after its initial run-in period with a1 the moving parts properly worn-in, when operating with the fully open throttle valve.
3. FEATURES 1. A compact, lightweight, and highly durable 4cycle aircooled EYseries with high output, embodying ingenious design and advanced machining techniques.

SEl -5-.
4-2 CRANKCASE The crankcase is made of aluminum die-cast and separable on driving shaft side with main bearing cover assembled. Provided on blower side are two ball bearings, each supporting the crankshaft and camshaft.
4-10 GOVERNOR The centrifugal flyweight type governor assures constant-speed operation at selected speed, irrespective of load fluctuations. 4-11 COOLING The cooling fan which also serves as a flywheel forcily feeds cooling air to the cylinder head with the aid of cylinder baffles and head cover.
5. INSTALLATION Since the installation method affects the service life, ease of maintenance, frequency of check and reapir, and operating costs of engine, the following contents should be carefully examined before installing your engine. For details, refer to the separate “SALES MANUAL”-Engineering Information-.

6-3-6 STARTING PULLEY and FLYWHEEL (magneto) Remove 3 pieces mounting bolts to detach starting pulley from flywheel. Remove flywheel from crankshaft. Insert a socket wrench or box wrench into an 18mm nut, and give the wrench a sharp blow with a soft hammer.
In reassembly; 1) Clean carbon and gum deposits from the valves, seats, ports and valve stem holes. 2) Replace valves, if badly burned, pitted or warped. 3) Correct the valve seat by using 45" seat cutter tool as illustrated in Fig. 6-3-3. The seat should be finished to 1.
6) ADJUSTING TAPPET CLEARANCE (Fig. 6-3-5) * Rotate crankshaft until tappet is in its lowest position, hold valve down and insert feeler gauge between valve and tappet stem. The clearance for both intake and exhaust, with engine cold. 0.13-0.17mm (0.0051”to 0.
In reassembly; 1) When reassembling main bearing cover, assemble governor lever shaft and governor arm before reinstalling them into crankcase. NOTE: If replacement of oil seal is required, force-fit new oil seal before reassembly.
In reassembly; PISTON RING (See Fig. 6-3-10) 1) Use a ring expander tool to prevent ring from becoming distorted or broken when installing onto piston. If an expander tool is not available, install rings by placing the open end of the ring on first land of piston.
5) Check if connecting rod moves smoothly after reassembly. Clamping torque of connecting rod cap is 250-300 kg-cm (1 8-21.7 ft-lbs). D (crankshaft pin Dia.) W (crankshaft pin Width) PISTON TO CYLINDER AT PISTON SKIRT THRUST FACE (CLEALANCE) (.0059”L-.
7. MAGNETO 7-1 MAGNETO In Models EY33-2 and EY44-2, ignition spark is furnished by a magneto. The magneto is composed of the flywheel, ignition coil, lighting (charging) coil, breaker assembly (including condenser). The flywheel is mounted on crankshaft, while ignition coil, lighting coil, and breaker assembly are directly assembled to crankcase.
For timing adjustment, the following alighment marks are provided: D type: D mark at lower left crankcase (see Fig. 7-3-1) M mark and slit on flywheel circumference B type: B mark at upper left crankcase M mark and slit on flywheel circumference. FLYWHEEL e- Fig.
*CHECKING IGNITION SPARK Remove spark plug from cylinder head and place it on cylinder head fin after connecting ignition cable to it. Crank engine several times by starting pulley, and check if plug gap spark is strong or weak. If spark is weak, check it according to steps 1 )-3) above.
8. GOVERNOR ADJUSTMENT EY33-2 and EY44-2 employ a centrifugal flyweight type governor which is mounted on a cam gear to automatically regulate throttie valve of carburetor by mean of a lever, so that the engine speed is kept constant irrespective of load fluctuations.
9. CARBURETOR 9-1 OPERATION and CONSTRUCTION (see Figs. 9-1-1 and 9-1-2) 9-1-1 FLOAT SYSTEM The float chamber is located just below carburetor main body and serves to maint ain the fuel I .eve1 at a cons itant height by a joint action of float (F) and needle valve (NV) incorporated.
9-1-2 PILOT SYSTEM This pilot system feeds fuel to engine during idle and low speed operation. The fuel fed through main jet (MI) is measured by pilot jet (PJ), mixed with air measured by pilot air jet (PAJ), regulated by pilot screw, and then fed to engine through pilot outlet (PO) and bypass (BP).
9-2-3 PILOT SYSTEM 1) Remove pilot jet (5) using a suitable tool while taking care not to damage it. 2) Detach pilot screw (6) and spring (7). In reassembly; 1) Clamp pilot jet securely, otherwise fuel leaks, causing engine failures. 2) If the tapered portion of pilot screw is deformed, replace it with new one.
10. RUN-IN OPERATION OF ENGINE after REASSEMBLY An overhauled engine must be carefully run-in to get proper engine surface conditions on newly installed parts. A thorough run-in operation is indispensable particularly when cylinder, piston, piston rings, or valves are replaced.
1.1. TROUBLE SHOOTING For a satisfactory starting and running conditions of a gasoling engine, the following three requirements must be met: I. The cylinder filled with a proper fuel-air mixture. 2. An appropriate compression in the cylinder. 3. Good spark at correct time to ignite the mixture.
11-1-3 ELECTRIC SYSTEM When there is no spark, the following must be checked. 3) 11-2 Disconnected cable leading to ignition coil, spark plug or contact breaker. Broken ignition coil winding, causing short circuit. Wet or oil soaked spark plug cable. Dirty or wet spark plug.
8) Restricked exhaust gas outlet. Carbon deposit in combustion space. 9) Engine detonating due to low octane gasoline with heavy load at low speed. 11-5 ENGINE KNOCKS 1) Gasoline of poor quality or low octane rating. 2) Engine operating under heavy load at low speed.
12. CHECKS and CORRECTIONS After dismantling and cleaning the engine parts, check them, and if necessary, correct them, according to the correction table. The correction table applies whenever the engines are repaired. Its contents should be thoroughly understood by those who undertake the repairing.
