No, the X-rings drop into the wells in the bowl to seal the primary extensions on the top housing. What rods appear incorrect? I might have spares.

What I meant?Is the primary extensions?Do they set on top of the quad?Rings or do they go in the middle of the quadrings when you put it together. The accelerator pump rod and choke pull off rod doesn't look the same... I am also missing the little spring on the choke assembly
 
The aluminum primary extensions have a flat that is sealed to the bowl via the quad rings. Just drop them into the two pockets in the bowl , making sure they are flat(not cocked). Do you have the torque sequence and spec?
 
I think I almost have it but something looks different about my accelerator pump rod compared to yours, but until I do the setting on the accelerator pump that might cmine just looks short. Compared to your pic

The accelerator pump arm is from the end of the arm to the pivot is inch and a half. And accelerator pump rod is two and three quarters from the end to the top of the hook.
 
If you want the carb to look nice:
- brush on domestic paint stripper onto the exposed alum parts.
- polish the black section with car polish

What year or casting number intake? A lot of carbs got goobered over the years. I'm fixing a 9800s right now. Always nice to have an untouched original for reference.

You can see the different acc pump set up on the 9XXX carbs compared to the 6XXX. The 9 series pump arm has slots in it for the pump rod, & the pump rod has a hook in it to engage in the slot. The 6 series has a different arm & round holes. It uses a rod that is secured with a circlip.
