Problem with 1850 French movement

[heifetz17]

Hey guys, it’s been a while since I’ve posted. I’m currently working on this silk suspension movement and when I have the plates tight the time train stops. If I slacken the plates even ever so slightly it takes off as expected.
Am I missing something with this? There’s almost no clearance between the barrel and first wheel and appears that’s where the binding is occurring.
Is there a spacer of some sort that is perhaps missing?

The strike train runs beautifully.

Never mind, found it! I’m embarrassed that I didn’t notice the strike train spring popped the back of its barrel open when I wound it causing the barrel to twist and somehow place pressure on the time train. All is well again now!

it’s good to be back!
