Good lead thanks! Found this, some fun info here, Zenith Model B style replacement for Model A but different venturi & needle valve. https://www.fordgarage.com/pages/nosbzenithcarb.htm

Do you know when the Tillotson X came out & when it got in the Ford books? My 1950 Ford Book shows the A carb xuperceded by the B carb, but no listing for a Tillotson. But from this thread & others, Tillotsons were on cars by 1960-62 so had to be in the 1950s somewhere

Do your headlights have 2 filaments like the normal 1928s or just one each?

I've been changing those carbs for literally 60 years & never seen a cork gasket there. A collector's item? One-Of-One?

Thanks thats a helpful PDF, though it shows only the 1928 (4+1) contact Rotary and the 1929-31 (9+1) contact Rotary. Here are pics of the Mystery (6+1) contact Rotary from the side, a 9-o-clock view as in the PDF, and a 12-o-clock view showing the slot in the top of the housing not in the other...

All those carbs! Back when I was age 6 my dad would always bring me home a $1 Zenith Carb to play with and squirt water in. That's how it began. By age 8 I had my 1st one running on the car. Didnt run too good but it ran. Even then I dont think we ever saw that many carbs all together.

I wondered that too. Dont see many 28s with cowl lights, I never used to keep track but dont remember any. Section 18 in Judging Standards shows Cowl Lights Oct 28 to Feb 29, BEFORE the Twolight setup came out. After that they'd be wired Twolight style of course like the well known diagrams...

Me neither. And yet, the forward stamped steel cap snaps right on there just as if it was a Model A part. Maybe it's a very early 1928 Mustang switch LOL.

Thanks again. The latest Judging Standard I have is 1989 & kinda vague. They just mention the August 1930 change from 62-7/8 to 60" length. My Dec 28 car measures 63-1/8 with a tape measure but that could be off a little. The ends dent in though as described, just not as much as the earlier 28...

Good suggsetion. I looked here, this has all the diagrams for 1932-40s, 1932-39 has the rotary switch but they all look like the 9+1 contact 1929-31 style, vs 4+1 contacts 1928 6+1 contacts Mystery Rotary 9+1 contacts 1932-39 I wonder about the Model T or Brand X? Link for 1932-up Diagrams...

"Could be the Jets" - Dennis Wilson, Two Lane Blacktop I noticed our A was running rich cuz I'd have to turn the choke mix adjustment all the way in. So tore into the carb, which had been rebuilt for my dad by somebody (I was 800 miles away). All the jet sizes were out of spec, mostly way rich...

Giving this a bump cuz I was just able to add the pictures. Hope they help.

Wow thanks for all that. It's been a while, my last Nationals was 2003 at Deatborn. Our car is 4 Dec 1928. I just laid a straightedge across from the bumper bracket hole to the end bolt hole. It's 10". The maximum depression in to the bumper bar is a "dent" of 0.5". From your 1st picture it...

If its any consolation, the whole CPI for prices is up almost exactly 10x since 1964 so its easy to figure today's prices from 1963-64.

All the OEM Model A's were either Holley or Zenith carbs (look the same, cast iron body, details differ like venturi and brass vs steel fittings). Tillotson was aftermarket, but I do wonder when they came out. We ran Tillotsons back in the 1960s so had to be before then.
