I also own a Solo 635 Chainsaw. Haven't used it a lot but it seems to be a very fine saw. I think the Solo Backpack Blower is ready for the trash. It needs Carburetor work, fuel lines and grommets, and the coil. What I like most is it was very powerful and the engine ran at a lower RPM than other Blowers. I never got a noise complaint using this Blower. My electric start Ryobi Blower RY-09600 gets random noise complaints. Out here in the Portland Oregon area, these gasoline Blowers will be banned in the next couple of years.
