Been using a pair of redmax bcz260ts' for about 2 years. Never so much as a problem or slow start. Today one finally decided to act up. Usually starts in 1 or 2 pulls, after 20 or so it started for about 5 seconds and died. And now nothing. Let it sit thinking it may have been flooded, still nothing. Replaced spark plug, near brand new air filter. Carb appears clean. Hoping someone can point me in the right direction so I can try and save $120 from the local dealer.
