So, I'm having problems with a DLE 20. This starts the third season with the engine and the first two were flawless. It was my best running, most reliable engine until now. It starts fine, and transitions well to full throttle, and runs great at full throttle, but after maybe 30 seconds of idle, it quits. Now, I don't know a whole lot about tuning gas, as a guy at the club helped me originally helped me tune it, and it was always fine from there, and I'd bet it's a tuning issue. I just don't understand why. I didn't touch anything over the winter. I tried replacing all of the fuel and vent lines, and even installed a new tank with no luck. I did, try leaning the low needle a bit which seemed to help a bit, but it still does it. Can anyone walk me through getting this thing running like it should again? I'd be forever thankful. Steve.
