Yes, look at the knob that holds the plastic cover over the air filter. If this is a 'round black' knob, then its an older version 026 with an air filter that leaves much to be desired. Look for one that has an 'oblong' black knob, this has the same air filter as the newer 260, plus an updated carb that compensates for dirt in the filter. You wouldn't think such a small difference in the appearance of the air cover knob would hold such secrets under neath. Then there is the 026 Pro that has an adjustable oiler and a decompression valve for easier cranking. Finally, you can get good 260/260 Pros for a reasonable price during the Summer; but, they all go out of their mind on ebay when it gets near firewood cutting time. Good luck.
