How to set fire to the engine !
Reading the check list you prime the engine with 5 or 6 shots of the primer ...........back to the list and you check the mixture is set to rich ........back to the list and you check the throttle is set........ back to the list and you put the keys in the Mag switch you take a good look around and yell "clear prop !" and put the check list down and turn the starter.............the engine fires once and you release the starter switch the engine kicks back and the prop comes to rest..............I wonder were that smoke is coming from ?..........S**T ITS THE FRONT OF THE AIRCRAFT !!!!!!!.........maggs off......fuel off ......mixture off .......master off............F**K off !!!!!!!!!.
How often will this happen this winter ? and all because of the "check list" being used as a "DO LIST" .
The time between the last shot of primer and cranking the engine should be as short as you can make it , the reason for this is that the fuel that you have shot into the inlet ports will run back into the carb and then into the airbox and then most likely into the cowlings , the shorter the time between priming and cranking the less chance of this happening.
Remember a check list is to check what you have done NOT a list of things to do!.
