YS140L Problem

[Karl G. Mueller]

Buddy,

Some of the little changes are hard to figure out wether they were done
on purpose or in some cases they just forgot the operation to drill a hole
in the crankshaft to provide lubrication to some of the suspect areas.
I have a 140L shaft that has a plug in it and one that doesn't, just the hole
in the center of the shaft going nowhere. Did they forget something or is 
it like that on purpose? Go figure!

  I have an L crankshaft that has an exit/entry hole bored into the hollow shaft located just behind the seal location. On the YS-140 Sport a hole in the same location provides case pressure to the diaphragm. I don't know it's purpose on the YS-140L, It seems that the hole was plugged on some of the L model engines. RE: Don Ramsey's post of a couple of days ago. Don says without the plug he is getting 300 more RPM with his YS-140.
