e. Cooling

System - Check

cowling, baffles

the cylinder

and, if found,

its cause must

be determined

and corrected

before

operation.

Heavy discoloration

and appearance

of seepage

at cylinder head

and barrel

attachment

area is usually

due to emission

of thread lubricant

used during

assembly

of the barrel

at the factory,

or by slight

gas leakage which

stops

after the cylinder

has been in service for awhile.

This condiiton is neither

harmful

nor detrimental

to engine performance

and

operation. If it

can be

proven that

leakage exceeds

these conditions,

the cylinder

should be

replaced.
