My vote is for the 028`s, they are as tough as a battle tank. The homeowners had more of them than most any Stihl chainsaw in their day and there is nothing worse than a regular homeowner that only needs a saw 3 -5 hours a year.Neglect ran rampant and those 028`s would chug to life each year to cut a random downed tree and usually a couple cords of firewood. They never seen any service til they quit cold and would come in with the airfilter plastered shut with old sticky oil and sawdust , most had no flocking left, the gas in the tanks was putrid, fuel lines melted into goo and fuel filters loose rattling around in the tank. With some cleanup, new lines and filter they went back out and ran again until they stopped starting. I have seen the same saws come back after 3-5 years in the same horrible condition just to be serviced over and over but the rest of the saw was super well built and with just a bit of care they would start and run every year. I have many of them that are still reliable starter/runners, kept cleaned and regular fuel serviced bits they continue to do duty when called upon. These days I have a stable full of 026`s and a few MS260`s, they were the replacements for the 028`s, ,they rev a bit higher and in some circumstances cut faster, weigh a bit less and are more ergonomic, fine saws in their own right. I see just as many of the 026`s neglected as the 028`s , they are also very reliable if just a bit of care is spent on fuel related parts, the carbs on any make of chainsaw suffers these days due to crappy fuel/gasoline additives so draining fuel and running carbs dry ,then adding canned fuel and start them up, let it fill the lines and carb if the saw is going to sit unused for months on end. The homeowner series of 170 and 180`s are just what they are intended for, occasional use and often discarded after not being cared for after several years but they can run very well if used frequently, fresh fuel used and of course proper fuel mix is used.
