Tillotson carb I had it rebuilt last year and it leaks internally. It did leak at the top seam but that has been fixed. It runs great except for the small leak. I checked the float and measured fine. I am confused about what to do next.

Re: Tillotson carb Find a Zenith. There are lots of them and they aren’t expensive. Tilly’s are notorious for warping and leaking.

Re: Tillotson carb Just where is it leaking ? Tilly's are good carburetors when in good shape. I think they run better than Zenith, but, not quite as nice as Marvel's.
The float can be set correctly, but, the needle may not be seating correctly/fully. There are several types of needle/seats, which do you have ? |
Re: Tillotson carb Micky -
I agree with Patrick. Tillotson runs very well. I cannot argue that the Tillotson is better than Zenith because I have never had a reason to change or a Zenith to compare. Our 1930 Coupe came to the family in 1957. It was equipped with a Tillotson and a spare Tillotson in a box of assorted parts. I completely rebuilt the engine in 1965. Over the years, I have rebuilt each the two Tillotsons a couple of times. The only times that I experienced leaks were when I did not get even pressure on the top screws and once when I had a bad float valve. Tim |
Re: Tillotson carb Tilly's are good carbs. Like Patrick said what type of float needle do you have. Buy a viton tipped float valve they work better with the corn gas we have to use today.

Re: Tillotson carb Get a Zenith and move on.
Years ago I tried to work with the Tillotson on a 31. It was just not worth the effort. Changed to a Zenith, never looked back. Our 29 has never had a leaking carburetor in 41 years. Zenith. Easy to service. One less thing to worry about. Enjoy |
Re: Tillotson carb Almost like talking politics isn't it ?

Re: Tillotson carb Gee, let's talk about what oil Micky should use! That's worse than politics.
Just after the carb was rebuilt did it leak, or is this something that just started? A tilly will out perform a Zenith any day. No reason to change. As noted above try a viton tip needle and see what happens. When you say you checked the float, what did you check? Shake it and see if there is anything inside of it. Check the float level so that it is 5/8", you will need a gauge for that. https://www.snydersantiqueauto.com/P...earchByKeyword |
Re: Tillotson carb To fix the warping, I fixed mine by baking in the oven at 250 degrees with "C' clamps!

Re: Tillotson carb I recently bought a rebuilt Tillotson and it works well. No leaks or other problems. Like TN Hammond, back in the 60's boxes of spare stuff was easy to acquire and in a box came spare carburetors, including a Tillotson. I put it on my stock Model A coupe and thought that it performed better, including better idle and improved torque, but the opinion was subjective, not based on any testing data. I eventually went back to the Zenith for some forgotten reason. I now think that the Zenith and the Tillotson are fairly equivalent, given that they both are in good shape. But, again, this is subjective and not based on any data.
The major advantage of the Zenith is that it is cast iron not pot metal. |

Re: Tillotson carb Yes, the zenith gauge will work but not as good as renners due to the shape of the tube. Go with Renners, he is a great guy to work with.

Re: Tillotson carb OK, then I will give you some advice. And that my opinion!:cool:
|
Re: Tillotson carb I took the top off the carburetor and it looked to be 1" from the top. I am still looking to see exactly where the gas is coming from.
