Just bought a br 420. I've always owned Echo, so this is my first Stihl. I read the instructions on how to start it and some how flooded out the engine trying to start it. It started fine at the dealer (service guy started it up before I took it.) How do I get a flooded 2 stroke to start? The plug has been cleaned, and I poured out the extra fuel in the muffler and combustion chamber. Any help would be appreciated.
