Engine BEARING Care and storage info.
Why pay $30 or 40 dollars for low grade or no grade factory bulk bearings that don't last long compared to Premium Industrial Grade ABEC3/C3 High Speed Bearings, get some spares if you leave fuel in your engine they will need replaced after they gum up or turn into a ball of rust, you can save buying a new engine by replacing gummy or rusted, stuck, rough or loose bearings before they come apart and damage the piston, head and sleeve. Save $$$ New Premium ABEC3/C3 Bearings make a big difference in engine performance. I always remove the fuel line and idle the engine dry, then put in marvel mystery oil or after run oil and spin it over, for long tern add liberal amounts of After Run Oil and cap off carb and exhaust, if the engine sets for a long time Not properly oiled it may appear to turn smoothly but some of the time the bearings aren't even turning, then when started the crank spins in the inner bearing race, not good.
