. BEARING's BAD? Why pay $30 or 40 dollars for a couple bearings that are econo ABEC1 with questionable clearance, get some Premium spares if you leave fuel in your engine they will need replaced after they turn into a ball of rust, you can save buying a new engine by replacing rusted, rough or loose bearings before they come apart and damage the piston and sleeve. Save $$$ New bearings make a big difference in engine performance. I allways remove the fuel line and idle the engine dry, then put in marvel mystery oil or after run oil and spin it over, if the engine sets for a long time it may appear to turn smoothly but most of the time the bearings aren't even turning, then when started the crank spins in the inner bearing race, not good.
