RE: Compression leak on ST 51?
Jester The secret of chicken stick starting is the amount of prime to get a cold engine started ,just like the choke on an old car. You can prime with a squeeze bottle or plug carb throat with finger and turn prop several times or plug exhaust tip and turn prop several times to get enough prime. I like the exhaust method because you don't have to jack with a small bottle of fuel and because of cowls and such you can't always get to the carb throat. By the way -do not put igniter on glow plug till after you prime good. We don't want it to start chewing up your fingers right off the bat..............as your turning the prop.
