I have a green (fuel/oil) mixture puddled in the throat of 2/3 carbs. What normally causes something like this? Thanks guys!<br /><br /><br />FWIW, I am leaking gas out of some fuel connections after the fuel pump. I am replacing the fuel lines tomorrow. What is the best way to crimp the lines to their connection? It had zip ties, this doesn't seem like the best way to do it.
