zenith carb
 

I have a zenith carb that for some reason does not have threads in the secondary well hole to screw the brass secondary well fitting into. Is that a normal carb or is it some kind of mistake?

I know nothing about the past on this carb. I came by it when I purchased a basket case model A . It has a single venturi in it now. Do I need a double venturi in it before it will work?

Look in the intake end of the carb,with the choke open.Are the two jets inline,or offset from one another?If they are inline it is a true double venturi,and if they are offset then it is a single venturi.

Bill C. is correct, early '28 carb, single venturi. Mine is the same and it's the original.
