If it started that easy with no choke, you may be running it a bit on the rich side. Does it run like a two stroke when you have a slight pull on it and break into a rich four stroke when you are at cruise? Or does it four stroke nearly all the time?

I just say this because I played with my carb(s) every which way and except when I had it set very rich, it wouldn't even try without some choke.
