Good to see you back on the forum, Eric!
Once you check the choke, and adjust if needed, and that doesn't correct the problem, you'll need to remove the carb, take the bottom(throttle) plate off, and epoxy the core plugs on the fuel bowl. They're leaking, and all of the fuel that is in the bowl is running out into the engine overnight, so there's not enough fuel in the bowl to fire it off first thing in the morning. Most Q-puke rebuild kits come with a small foam rubber-like "pad" that fits down in the throttle plate, to seal these core plugs, but they don't work very well, or for very long.
A smidgen of JB Weld will usually resolve the leak. I usually take a
small hammer and peen the plugs a little first, just to seat them back up in the body of the carb, then mix up the JB Weld, and schmere it over the plugs. You have to watch how much you put on there, because the bottom(throttle) plate has to bolt back on, and if you get too much epoxy on the plugs, the plate will not sit flat, and then you've got another problem all together. What I do is put the epoxy on the plugs, and give it a few minutes to harden up a bit...enough that it doesn't smear off easily. Then, I'll sit the bottom plate on there, and mash it down with hand pressure. That way, when I take the plate back off, I can see how much epoxy is enough. If there's too much to let the plate sit flat, then I have to wait until it hardens completely, then use a good mill file to file the epoxy down a little, until the throttle plate will fit nicely.
