Please tell me you've been taking pictures?
A couple of things that I forgot to do;
1. Prime the carb. I forgot to at least put some gas in the float bowl, killed the battery trying to fill it. (I know, I'm and idiot)
2. Set the idle air screws. Hand tighten the idle/air mixture screws all the way in (only hand tight!!!) Then back them out about two full rotations, that is a good place to start.
3. Make sure that the choke is set. Because once this carb is on, you can't get to all three of the the screws to loosen the retainer ring around the choke. That means you have to take the carb back off to adjust the choke.
I think those are the big ones that I had to figure out after the fact. Let us know when you get it fired.
