<DIV>To check the main bearing: When the engine is warm, rock the prop
back and forth. A <U>very</U> little play is OK. Anything more needs
replacing. It is unlikely the front bearing needs replacing. I
always ran my 140 1 turn out on the HE needle. I would start with the low
end needle. 140's have always run rich on the low end.</DIV>
