the coupe is gravity fed, the pump only transfers fuel from the wing tanks to the header,

Thanks once again Matt.
This morning a friend shared, "Stromberg Numbers Game" by Robert Kachergius. From his writeup I see the 167 as being gravity and the 172 as "pressure". Is pressure referring to fuel pump pressure?
Another friend has a 167 ready for me, but I wasn't sure I could use it on an Ercoupe...Can I?
Thank you!

Carburetor Question was created by Shawn DUFFEE
Hello All!
my C85-12 (did not come with the plane and is still not mounted) has a Stromberg NAS3-B carb. It does have the mixture do-dad, safety wired off.
My understanding is I need a NAS3-A1.
These seem hard to find.
Would a Marvel 3SPA 4240 work on an Ercoupe?
Thanks,
Shawn
