Working on my F12 and took the carb apart.
I want to put a kit in it and this carb doesn't have a venturi in it.

Were they supposed to?
Thanks
Mike

Mike none of your kits will include a venturi. Are you needing one?
 
I'm thinking that I do
There wasn't one in the carb
Just wasn't sure if they had one

Do you have a picture of a carb apart with a Venturi?
Thanks

Is the lower half of your carb a brass body or cast iron?

The outer design of the two is basically the same but internally are different. As far as the venturi goes it's completely different between the two style of carbs.
 
It's brass
3927-DB is cast number[/quote]

There's a picture of what you should have. I rebuilt that carb and first used it on my f-12 after rebuilding the motor. The delivery nozzle goes through the Venturi on the brass carbs. On the cast body carb they're separate.
 
Now I'm going to have to look at mine. I've got mine torn apart trying to solve a leaking throttle shaft. My brass bottom carb is flush on the top. Doesn't look like that at all. Maybe that's part of my problem too...
 
I've got my brass carb torn down now to try to solve a leaking throttle shaft issue. I don't think mine looks like that either...I think it's flush on the top. Maybe that's part of my problem. I'll look tonight when I get home.
 
The venturi is on the bottom of mine, 29953DB is my carb number. Looked to me like there were a couple different variations.
