Fresh mill. Bad happenings? What to check for?

Good happenings today. I replaced the new thermostat with my good 180 degree with hole drilled. Burped the system per 67Dart273 and fired it up with heater on. Thermostat opened up as it was supposed to and temp stayed nicely in the operating range. Ran for about 10 minutes, cooled down and topped off. Antifreeze is in. Ran it again for a few minutes.
Raining today so no drive yet. Still running great.
Now....with that said, I am still concerned that I am getting some condensation out of the exhaust. Started off pretty wet but was probably residual from the first start up. I does lessen as the motor warms up and second start was not heavy initially. No smell of or feel antifreeze. Hoping that a nice drive on a warm day will put this to rest.
Thanks for all of your help.

For every gallon of gasoline through the carb, about a gallon of water comes out the exhaust. This especially noticeable on cool or cold days during cold start warmup. With the choke on, much more fuel is going through so more water out. When the choke comes off it leans out and the water produced is much less. While the exhaust is cool, the water condenses in the muffler and tail pipe. Every muffler should have a 18" hole to let this dribble out. After being well warmed up the water stays steam and out the tail pipe.
