I bought a SRM-225 to use on my residentials, right away there was oil coming out of the exhaust after use.. no big deal, I keep on using it... I notice that it is having trouble getting gas while edging beds, the fuel bubble runs out of fuel and it dies.. so I take it back to the dealer to talk to the mechanic.. He says ya gotta run it at full throttle to ensure full combustion to keep the oil out of the exhaust, he says there was a bend in my fuel line that may have caused the fuel starvation while edging. So I go on and use it again... same problems.. by this time the trimmer is about 5 months old so I buy a fuel line kit and change out the fuel lines/fuel filter. still same problem... so I thought maybe I had a lemon... I go to HD to buy the same one and guess what within two days I have the same problems... I call Echo and what do they say? run it at full throttle... I took it back to HD for a refund and the lady laughs and says " yeah we had two others returned today" she points across the way where two other SRM-225's were... Echo knows they have a problem and have decided to let it go... STAY AWAY FROM IT..
