Echos are great little engines and I love them. Well, the big ones too....

Don't feel bad about that carb. You did good. I am somewhat of a carb expert on most all types of carbs and have rebuilt hundreds of carbs on everything from full size cars, boats, and airplanes down to Walbros, Zamas, and little glow carbs, and even I will come up against a carb every once in a great while that just won't seem to work right no matter what I do. When I finally get aggravated enough I just throw it in the scrap box to be used for spare parts.
