need a matching 1920 carb for my manifold

The numbers should be stamped into the top of the main housing between the fuel inlet and bowl vent.


Cool thanks. I found em
the one I'd need to match to is.
12r4328b (1920)

the one I really like but need 2 of em is 12r55928

this one has a vented return on it, it seems like it would be better to use do to me being able to add a return vent to the tank/canister for fumes. but it's got a horrible throttle shaft leak.
I'll pm ya also
