For just normal after flying use, I just dribble some auto trans fluid into the carb, and then either spin the engine over for a moment with the starter, or flip the prop several times. I have a "3 in 1 Oil" can that I emptied, pulled the plastic cap off, and filled it with auto trans fluid. It is handy because of the little pull out spout it has which allows you to control how much you are putting in, and then easily closes for safe keeping.

If I have one I am going to store for a while, I usually pull the spark plug and shoot a little in there as well and then turn it over to distribute it. Remember to always run the engine dry of fuel first...
