    Yes, the leak is from the low speed venturi when I prime, just a little fuel running down the front out of the whole. I saw the same watching a few YouTube videos of HD20s and 25s running. When I shot the fuel in with the syringe, it very briefly fired, I mean like each cylinder maybe once or just one cylinder. But you could hear it, and get a quick whiff of exhaust. If the low speed needle packing is truly gone in mine though, could this be the problem? How many turns out should I have the low speed needle?
