Exhaust pipe is 1-1/4" iron pipe size. It should be installed without sharp bends and slop downward to its
outlet to discharge water. The connection for discharge water should be at least 4" below the bottom of the
manifold exhaust flange opening. See Figure 1.
Suggestions before starting your new engine:
CAUTION: ENGINE IS SHIPPED LESS OIL. FILL WITH SAE 30 CLASS A DETERGENT OIL
BEFORE STARTING.
Ventilate engine compartment by opening hatches and starting blower fans if you have them.
Check fuel supply and make sure fuel lines are tight. Any fuel seepage or leaks should be corrected before
you attempt to start engine.
Check all electrical connections. A wiring diagram for your particular model is included in this book.
Ground is negative. Ground terminal should be attached to engine block.
Do not allow flames or sparks near battery openings. Gases produced during normal charging are explosive.
Make sure water pump is lubricated with water pump grease.
Starting you new engine:
1. Clutch lever should be in neutral position.
2. Fill fuel pump bowl using the hand primer on the fuel pump.
3. Place throttle lever at ¼ open position.
4. Pull out choke rod.
5. Turn on ignition and start engine.
6. As soon as engine starts, gradually push in choke lever until choke valve is completely open.
7. Run engine at idling speed of 600 to 1000 rpm.
8. Check oil pressure - 45 to 55 pounds when engine is cold. Check oil after about 10 minute of running.
Add oil to bring level to full mark if needed.
9. Check cooling system and make sure water pump is operating by checking water out of exhaust pipe.
Temperature indicated on gauge should gradually go up to 140-160 degrees.
10. If oil pressure or water flow (or operating temperature) is not normal, stop engine at once and check
installation to correct problem.
11. When shifting into forward or reverse position, engine should be running at 600-1000 rpm.
