Very possible

SS Minnow - The hyperlink above doesn't work. Sorry.

Damn, just seen this. I will try one more time, just differently. Here goes:

Hopefully that works as they are good reads, pun intended.

After you find one of the vacuum lines fell off .. come back and tell us what color it is ...

Make sure the throttle plates are closed at idle. Anytime you disturb a carb you should check and make sure the "synch" wasn't upset.

Well folks, I think I found the problem. The reed block gasket on the top, starboard side had slid in and there was a vacuum leak on the #1 cylinder at that point. I took apart the whole reed assembly to check it out, and put it back together with new gaskets. Hopefully, tomorrow I'll get to test run it.

Great! Glad you found the problem!
