I too asked this same question of my father. as I don't have alot of expereience yet, and he does. I noticed that alot of his old stuff he gave me had the bar on them, and the newer stuff didn't. His explanation of the idle bar was very similar to the one EXCAP gave you. Back in the day, he used alot of plugs with an idle bar racing at your fields, usually bringing home your trophies, [sm=lol.gif]and all that from a guy who didn't even know how to tune his engine! That was pretty lucky huh?
