well axeman I've explained it three different times ,and will do it again since you asked.After each day of running the engine I disconn. or drain or clamp off the fuel to the carb.conn the igniter to the glow plug start the engine after it has ran all the fuel out then reconn the igniter and spend the engine over some more to make sure all the fuel is used up.If a 2s add dozen or more drops of afterrun through the carb,if a 4s then same through the vent nipple,turn the engine over ,you are coating the bearings,if storing for a long period of time ,then do the same also remove the glow plug and add oil there,couple of drops of oil doesn't do much ,you are trying to desplace the fuel and residue with oil to stop the rust and corrosion.
