No gas smell, I'm afraid.
A weird thing is how hard it hits at idle. You can feel and hear the right exhaust being louder and hitting harder. The left side is just as you'd expect and not too harsh.
I'll double check my choke but it hasn't changed ever and has replicated all the other carbs I've done. I think there's even a little dot that indicates which way things point.
I'll switch to normal mixture and lean it a fair amount tonight and report back.

1 last thing. When playing with mixture screw, as it is now, leaning or richening has zero effect over the idle on the right side. Leaning it all the way in doesn't bog or kill things, same with all the way out.
The left side is pretty sensitive and bogs and even kills the bike if too rich or too lean (normal behavior.)
