the more saws you own the more you have to be aware of, I only have 4 saws and its always in the back of my mind what saw has sat the longest and how can i get it some run time. today im going to use a 592 on a 16 inch fir tree because it hasnt been used in 2 months and I need to cycle some fresh fuel through it, its not the ideal saw for the task, but I dont want any issues with it so I will use it instead of just let it sit for who knows how long and risk having problems.
i saw pretty consistantly from april through december, when I am putting them up for the year I dump my 40:1 dominator out and fill with canned husky mix and run them for a few minutes to assure the canned fuel has fully made its way into the carb. than I hang them on the rack and let them sit, thats been my recipe for a few years now and its has worked fine, no issues what so ever.
