with engine removed, i put a piece of fuel line on the carb, plug the exhaust port and carb inlet. then while blowing in the fuel line i immerse the engine in a bowl of soapy water and look for the bubbles.

just like that except i use a squirt of simple green on the bearing and tip the motor up. if you blow and it squirts in your face, change em out. if you blow and it barely makes any bubbles and is hard to get air in the bearing may be fine. i have used the avid double sealed bearings with great success. also tighten the flywheel nut as tight as possible.

"also tighten the flywheel nut as tight as possible."[/QUOTE]

Without breaking the crankshaft off. I tightened the flywheel nut to tight on a new OS speed and twisted the end of the crank off a few years back.
