I have a 2006 SRM-261-t. It worked flawlessly till August. It wouldn't start,so I do the basic checks, then take it to the dealer. He calls a week later and I get it back with a brand knew Carb. He said the new design of the carbs make them where they can't be fixed, They must must be replaced. A week later, the same trimmer bogs down when I pull the trigger. Drop it off and guess what, the carb if messed up again. When I pick it up he tells me echo gave him a tough time covering the repair. Ironically, my old SRM 210 works great, not a problem. Is anyone else having simular problems with echos?
