I almost forgot.


When you put your RC car/ truck / airplane away for an extended period of time...it wise to use after run oil in the engine to prevent such a problem. Go to your automotive parts store....or Wal Mart and buy Marvel Mystery oil. When your ready to put your RC toy away...remove the glow plug and squirt several drops of the oil into the cylinder. Move the piston up and down so it's well coated. Replace the glow plug. Then squirt several drops into the carb and again.....move the pistion to help coat the crank, etc.

Some guys will add the oil and with the glow plug removed....will try cranking the engine several times. Be sure to place a rag over the top of the cylinder if you do this as the oil will spit out at you. The idea is to get everyhing well coated to keep varnish from building or for moisture to damage anything internally as the left over fuel acts like a magnet for drawing moisture into the engine which could damage it internally.

Good Luck!
