I was wondering if anyone on the forum had an Echo CS-352 chainsaw. I bought this in the beginning of the season to cut up scrounged wood for my woodstove install coming up and I decided to check the air filter. The saw has performed flawlessly since I bought it and still starts right up. This is the type of air filter where you just "twist" it off of a plastic manifold. I took a look at the filter and was surprised to see how dirty it was after just this one season. I took the filter off and was even more surprised to see that a bunch of oil soaked saw dust got past the air filter and caked up in the plastic intake manifold. Any suggestions? I was thinking of getting a new filter and using an RTV sealant on the flange before twisting on the new air filter.
