I have not pulled the idle mixture screw out. I turned it all the way in and backed it out 2 3/4 turns. I'll yank it out and look around. I'll definitely check the float needle and height and adjust if necessary.

There is fuel in the bowls and it flows free if I open the drain. I'm just going to have to take the plunge and take the whole assembly apart.

Sometimes you get the bar, sometimes the bar gets you.
