Alright guys, Today was only the second day I have even tried to start my new Stihl BR420. Last time, I tried for like 20 minutes, then it started and ran like a champ all day. Today, I spent 20 minutes at my first property before I broke out the push broom. At my second property (mom and dad's house) I spent about 1/2 an hour trying to get it to start before the push broom came out. Finally I just decided that it was a push broom kind of day, but I can't figure out what's wrong. I've tried replacing the spark plug, removing the air filter and cranking it, choke, no choke, full throttle, minimal throttle, and everything else I can think of. Any ideas before I take it back to the dealer?
