Hey everyone..I'm relatively new to outboard repair but I have a question about an evinrude fuel system...<br /><br />I'm trying to get my engine running right after it's been sitting for a few years...it fires up and runs fine, but won't idle right unless i'm manually playing with the throttle....I've noticed a red, triangle-shaped lever on the left side of the engine that's part of the fuel system...the engine seems to run better when I turn this lever counter clockwise, but not too far...is this some sort of a fuel shut off switch? Where should it eb set? It also looks like there's a valve coming out of it like you'd see on a tire's valve stem...what is that for?<br /><br />thanks for any help!
