I remember that too. I'm sure Dr. Al fixes that early and often. I think it's the pleat in the boot. I've been wrong plenty of times though...I remember seeing some pics of the 026 jug intake port showing the little lip that caused the puddling/idle issues. I think it was Stihl that said to grind out the little lip to solve the issue.
Gotta see if I can dig that thread up.
