For safety reasons, it is recommended that the following items be checked each time before
operating the engine:
-
Starter (check connections, installation, and condition; correct if necessary)
-
Carburetor (check connections, installation, and condition; correct if necessary)
-
Ignition (check connections, installation, and condition; correct if necessary))
-
Fan (check installation and condition; check condition and tension of fan belt; correct if
necessary)
-
Cylinder heads (check installation and condition; correct if necessary)
-
Cylinders (check installation and condition; correct if necessary )
-
Exhaust manifold (check installation and condition; correct any discrepancy)
-
Muffler (check installation and condition; correct any discrepancy)
-
Spark plugs and plug caps (check installation and condition; replace if necessary)
-
Fuel system (check for leaks and dirt in filters; repair or change, as necessary)
2.3 Starting Procedure
1. Fuel supply (insure tank is full and fuel valve is open)
2. Use choke if engine is cold, but not if engine is warm or hot.
3. Set throttle at idle (carburetor slide should also be at idle position)
4. Close ignition circuit (Turn ignition switch to ON-Position )
5. Start engine (use starter for maximum of 10 seconds)
6. If the cold engine will take the gas, the choke can be retarded (check by advancing throttle
lightly)
7. Allow engine to warm up for 3 minutes at 1/4 power (ca. 3000 rpm).
8. When it reaches operating temperature, engine is ready to go.
If the engine is or should be later equipped with a centrifugal clutch, the following procedure
must be observed:
1. Warm up the engine with enough RPM to keep centrifugal clutch fully engaged.
2. Accomplish the warm up phase without allowing clutch to disengage.
revolutions are very low, with clutch not engaged, the warm up will take longer.
If the warm up or other engine operation is carried out in the range where the clutch engages,
the result may be increased wear on the surface, glazing of the coating, or overheating of the
clutch.
