Engine StorageTips
Storing
The Engine:
Using proper storage techniquesare not only a good habit but are criticalto the life of the engine. Nitro fuel contains castor for lubrication.If it is not bumed out of the engine completely,over
time It can gum up and damage the crank beanngs. We recommend using your fuel bottle to drain all remaining fuel from the tank. Use a fully charged igniter and fry to restart the engine to
bum any excess or remaining fuel out of the lines. Repeat this step until the engine will not start. After buming off the fuel, remove the glow plug and add several drops of engine maintenance
oil then crank the engine over to spread it throughout the engine. If you plan on storing your engine for long periods of time (more than 3 months), the maintenance oil may gum up as well but
will not damage the bearings. To restart engine, use 70% Isopropyl Alcohol or Denatured Alcohol and cycle it through the engine using the pull starter or roto start DO NOT TRY TO START
THE ENGINE WITH THE ALCOHOL! The few minutes you take to propedy prepare your engine for storage can add valuable time to its operatinglife and maintain its optimum performance.
