Well there does seem to be conflicting opinions here. I do need to make one correction, however. My engine is not a YSB, but rather an SB. I just learned that a YSB is a horizontal cylinder. My surveyor
and some of my paper work said it is a YSB, but apparently not so.
I am still not certain what to think. The clutch is definatly a "wet" clutch and it seems that might imply that the flywheel would pick up oil which would in turn get into the starter. My starter seems to run fine so far with oil on the armature. Different mechanics I have spoken with (even Yanmar
mechanics) have different opinions. Some say it won't hurt anything, some the opposite.
The face of the starter DOES HAVE A GASKET
which implies that oil should be present.
Any other thoughts?
