As soon as the engine starts you need to progressively ease off on the choke.. It'll run without the choke very quickly depending on the air temperature.. These do tend to run a bit rich at idle..
Thanks. I actually mean that it smells gassy anytime I'm at low speed. I'll get home and pull into the driveway and I'll smell gas. Maybe it smells gassy all the time but I outrun the smell at street speed.
