Lubrication

All the parts of your engine are automatically lubricated by the oil content of the fuel mixture. The crankcase breather hole is in the bottom of the timing case and is fitted with a brass nipple. Fit a length of silicone tubing of approx. 2.5-3 mm I.D. to this nipple to conduct the small amount of oil that escapes through the breather away from the model. Do not block or obstruct in any way the breather nipple.
