Not all completely accurate.
Plugging the exhaust isn't the preferred way to kill the engine. Plugging the exhaust will flood the engine which can kill plugs and make re-starting more difficult. Bumping the flywheel is a much better method.
Running at or under 250 degrees is not always the case. Some engines run hotter than others. Tuning by temp is one of the worst habits you can get into with nitro engines.
Running fuel with too much oil can be harmful. Most RTR blend fuels have way more oil than needed which only robs power and does no good really.
My opinion.
