Engine Storage Tips
Storing The Engine:
Using proper storage techniques are not only a good habit but are critical to the life Of your engine. Nitro fuel contains castor for lubrication. If the castor is not burned Out Of the engine, over time it can gum up
and damage the crank bearings. Using your fuel bottle, drain all remaining fuel from the tank. Use a fully charged igniter and try to restart the engine to burn any remaining fuel out of the lines. Repeat this
step until the engine will not start. After burning off the fuel, remove the glow plug and add several drops of after run 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 after run oil may gum up as well but will not damage the bearings. To prepare the engine for re use, 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!
