This saw worked great,and cut 4-5 cords in the 8 months I've had it. Just the other day, I was cutting with no problems, stopped the saw for 10 min., whent to restart and - nothing. Maybe heard a slight 'pop' when I tried to restart, might have been in my head?! Anyway, it has fuel, it is getting spark with the plug out of the cyl, I even gave it ashot of starting fluid in cyl and replaced plug- no start, no smoke. Before I toss it for a sthil, any suggestions?
