Switched Carbs: choke rod doesn't line up
I just picked up a rebuilt Tillotson Model X, and swapped it out with my Model B Zenith. The choke rod doesn't line up right and it's not a smooth pull.
It never really lined up with the zenith, it was off just a little, but now this is out of whack by a lot. I can make it work, but I won't leave it like this for long. Any suggestions? Is there a difference in intake manifolds? |

Re: Switched Carbs: choke rod doesn't line up
Model A & Model B carbs are different and won't line up unless you use the correct manifold.

Re: Switched Carbs: choke rod doesn't line up
Front engine mounts could be shot. Does the crank hole line up?

Re: Switched Carbs: choke rod doesn't line up
Good Morning...The bolts in the kit have had their shafts turned down a bit in the center so that the carburetor can swivel a little bit and line up. The kit works, if you have a lathe, you can make a couple...Ernie in Arizona

Re: Switched Carbs: choke rod doesn't line up
The model B carburetor has a larger throat but the bolt pattern is the same as the model A . If the intake manifold runner is enlarged to model B size you will benefit from the larger model B carburetor . If the larger model B intake is used it will cause the carburetor to be at an angle that won't line up with the choke rod . unless the kit above is used . I once cut the flange off of a model B intake , turned it to the correct angle for use on the model A and brazed the flange back in place .

Re: Switched Carbs: choke rod doesn't line up
It didn't line up right with the Zenith, why would it line up with the Tilly ?
Maybe the frame is sagging, body blocks bad ? To get by..... removing the rubber grommet inside the car just might work, the choke rod would rattle!

Re: Switched Carbs: choke rod doesn't line up
When the model B intake manifold is used , the position of the carburetor doesn't point in a straight back manner like it would if the model A intake manifold was used . The flange that the carburetor mounts too causes the rear of the carb , where the choke rod connects to be at an angle that doesn't line up with the choke rod .

Re: Switched Carbs: choke rod doesn't line up
The Model B carburetor was made for a Model B (1932-1934) Ford. It was never used nor designed for a a model A , and it used a flexible choke cable. The Tillotsen you had on your car was actually made to be used on a Model A.

Someone else mentioned if the crank hole is lined up. It is, so I'm not too worried there. Best case scenario, it's the body on the frame wonky, I fix that and the Tilly should line up. I hadn't thought that it could be this. Thanks guys! |

Can you post a picture of the intake manifold you have?

Don’t bend the rod. You can’t turn it with a bend in it.

No harm meant but I believe that the model B carburetor with a smaller venturi was sold as a replacement for the Zenith one and two carburetors on the model A . |
