I picked up a well used 268 yesterday. 2 issues/questions so far...... Not sure what sort of air filter set up I need/ Some previous owner cut a round hole in the air cover and put on a foam stack that was disintegrating into the carb. Will try to attach photos of air filter holder setup. Also, does not seem to have spark although I think i will buy a simple tester today. Has anyone had success with aftermarket coils? I found a bunch on ebay that seem to be compatible with many older husky saws for stating around 11$ and on up . Also seems to have a tillotson carb i would need to rebuild, anyone able to guess which model that would probably be , or which carb kit? Trying not to put too much money into this saw as I dont think I will keep it ( pretty happy with my old 365) Thanks for helping a newbie
