Venturi Removal
It seems to be one thing after another rebuilding 2 carbs and learning more as I go.
One of my carbs has a frozen venturi in the top half. It will not budge.
I have seen the home made venturi extraction tools but nobody shows how it works.
I may need a press.

Soak it in WHITE Vinegar for a day or two to disolve the rust that is holding it in.

Re: Venturi Removal
If you search Fordbarn I know there have been threads on that. I think some suppliers may sell them too. Have you tried heat? I think most pullers are a piece of pipe or a socket, a bolt or threaded rod, a washer with two flat sides and a nut.

Re: Venturi Removal
I see the tool but nobody can show me how to use it.
I will try heating up the parts and dunking in cold water when time permits.

Re: Venturi Removal
From what I've read, the venture is made of pot metal and should be soft. I do have a new one.
I will try the vinegar bath tonight before trying the heat.

Re: Venturi Removal
if that doesnt work we had to use a bare hacksaw blade and make a slit in the side of it and pop it out that way. Mine did not want to come out of its home haha.

Re: Venturi Removal

Heating is OK if done carefully. BUT DO NOT PUT IT IN WATER WHEN IT IS HOT. This will make it brittle.

Re: Venturi Removal
No movement and the vinegar only discolored both parts and stunk up the place. I will try heating the body and putting dry ice inside the venturi and see if both metals go in different directions.

Re: Venturi Removal
You have to soak in the WHITE vinegar for at least 24 hours.

Re: Venturi Removal
Look it all over closely. You may not have to remove it unless it's damaged - if so, then just smash it out of there. I made the removal tool and it works great some of the time, but once in awhile it really tears up the top portion of the venturi. You might just shine it up carefully with some 000 steel wool. If it is that bad, you'll likely find much more of a problem with the secondary well. Study, collect, and make the carb tools you'll need - winter is coming, and you can enjoy working on them through the cold weather. Good luck
