AHHHHHHH I hate them! I always take them out when I buy new equipment but for some reason when i got my Echo backpack last spring I forgot to take it out. Yesterday it just got slower and slower and today it would hardly run. I knew then what the problem was. Took it apart and sure enough it was 100% clogged so i threw it away and put the blower back together. Started right up and blew harder than ever. Anybody here take there's out? Or anybody just never had any problems with them?
