Extreme Temperatures

If you are using your engine in extremely hot weather, you may find it ne- 6 cessary to lower the nitro content in the fuel and/or install one of the extra head gaskets under the cylinder head to lower the compression ratio. In both cases, this will help the engine run cooler and prevent it from cutting out or detonating due to over-compression. In cold weather environments you may find you need to do the opposite. Use a fuel that contains from 25% - 35% nitro content and use only one head gasket in the engine. Using the higher nitro fuel will help improve engine starting and ease tuning in cold weather.
