The soldered lines blow out clear with lots of carb cleaner flowing through them. The Bendix service manual (I use that term lightly) only says to ensure the soldered connections and welch plugs are sealed. Which they seem be when light pressure is applied. On a side note, I think this is a “pressure carb” developed for aviation. Once I have it working correctly I should be able to run this motor inverted without any loss of performance 😀

That’s a good tip, Mumbles. I did catch that right away, but it’s worth mentioning for anyone else that may be following along.
