I bought a Stihl FS55R brand new the other day. The guy at teh shop showed me how to start it, and it started at the shop. Now I cant get it started for the life of me. I even look in the *gasp* manual, and followed that, but cant get it started. Any insight? I was hoping to have an extra trimmer on a job Im doing tomorrow, so if I can get this thing started it'd be nice.
