You dont know what you are talking about. For one, an ms 290 isnt that bad of a saw IF taken care of. Granted it aint a pro quality saw, but works for intended use. Two, 260/026 too old of a saw? Where the hell do you get that from??? 026 is one of the very best and easiest of saws to work on ever made!
Well, everthing "works" for intended usage if the requirements of "works" are low enough. For you it might work, for me it doesn't. I wrote: "that's what I think". For my work, the saw doesn't work.
Concerning the 260/026. I have a 026 myself and yes, it's a good saw. It has been a real work horse for me. Some problems with fuel caps, filters and a broken handle etc over the years but nothing serious. But I also have 353 Husky and I can tell you there is a difference between the two. But there are som years of development between the two also. The 260/026 is a good saw but time passes by and the 246/353 is a better saw. Would you buy an unused but 10 year older car for the same price as a 2007 model?
