After a good sleep, we returned to find gas puddled all over the manifold. That's what we get for installing the carb without rebuilding it. We were shocked at how much we had to spend for new accelerator-pump diaphragms, which were the problem. Once it was running again, the fan belt squeaked badly; it had stretched, and the alternator bracket had no more room for adjustment. Off to buy a 1/2-inch-shorter belt.
