Note:
For break-in a smaller propeller is recommended.
Important:
1.Remember that when the engine running ever person must stay behind the line of the
rotating propeller; never to the side or the front!
2.The engine needs 12-20 hours running time for the break in process to be 100%
complete.
Engine Cooling
A proper cooling system is vital for any engine. An air cooled engine requires an
appropriately sized air intake. Also to keep this air cooling process working the
incoming air must be exhausted. Further, the exhaust air outlet should be four times
(4X) the size of the cool air intake.
Example:
. 10 square inches of air intake area would require
. 40 square inches of exhaust air outlet area
It is up to you to insure that the air flows freely to, over, and away from, the hot
cylinder(s) and muffler(s). Please refer to Engine Installation for motor box
considerations, and to the following tips on baffling.
