I appreciate the pics, John!

It confirms the needles are the same as the M53 series;
The main nozzle is captured with a plug (like Type A Scheblers), and I'm curious if it differs from the M53 series which seem to vary greatly!:

It would also be great to know if there was a spigot seal,

And the degree stamping upon the throttle disc (if original) would be delightful.
(The inspection stampings on the bottom the flange are rare, except on Scheblers!)

Can you see an opening at the bottom of the bore, directly behind the venturi?
(Here's an M53A-1 with the venturi removed; I doubt you will see one, but I'm curious how the M53 series evolved..)

Thanks!

Cotten let me know if this is what you'er looking for or if I missed something. These carbs are new to me.

There should be a main nozzle above the spring, John,

And it probably looks something like the short one in my #33 pic.

Sometimes, you gotta pull them (the bombsight might require creativity),

I am surprised by a 12° disc, and wonder if it came with the Euro throttleshaft. (They are quality, but I remove the O-ring at the bottom.)

Inspection would be for daylight around the disc when completely closed, and with the idle bleed plug on the side removed, observe if the closed disc falls in the middle of the slot.

PS: You might want to swipe the manifold flange across a flat abrasive for inspection.
