Engine is full of gas again. I suspect the float valves are not working properly. I can give them (another) good cleaning.
At $11 each I suppose I could just replace them - What's the likely-hood of them being worn out or beyond cleaning?
Again, be forewarned I am not a carb guru, at least not yet. But it sounds like at least one is sticking. But, the bigger question is why its getting enough pressure to allow gas into the bowl even with the float stuck? Combined with the dead battery, it sort of sounds like the fuel pump is staying on for whatever reason. I had an old T-Bird that did this very thing, but I had stupidly tried to regulate the stock FI pump pressure down to carb pressure when I converted it to a carb. You don't somehow still have the computer and FI pump still hooked up, right?
Easy fix would be to start with rebuilding the carbs. As you said, the kits are cheap, and its only a couple hour job. Probably worth it.
