I have an os 51 four stroke mounted on an elder 40. Due to the design of the plane, I cant get to the carb to choke the engine. When the engine is cold, I put my finger on the muffler, flip the prop a couple times and the engine is primed. After i run the engine, I learned the hard (and stupid) way that the muffler gets REALLY hot.. How can I prime the engine after I have ran it?
The simple soulution is to put a small piece of silicon exhaust deflector on the muffler exhaust pipe. That is what I have done.
When starting a hot engine it is usually not necessary to prime it, flipping it over smartly should be enough.
There is no need to use an electric starter, but I strongly recommend that you use a chicken stick
