I got these 2 trimmers of Kijiji last night for free, but neither of them work. I come looking for what I should do next.

The older trimmer had no fuel in it so I am yet to try and fix it. The newer one will start at full choke but not run at any other amount of choke or for very long at full choke. Mixing up some new fuel tonight and will check the spark and such.

Any tips from you Oppo's?
