We have one our 29. Runs really great.

Tried a rebuilt original that I ended up replacing with the new Zenith.

They are expensive for a reason.

Enjoy.

Bought one when they first came out for around $250. Ran great the first season, but wouldn't start the car the next spring. So took it back to the vendor and he had it "rebuilt". Don't know exactly what the rebuilder did. Running great ever since. Vendor told me that all of them need to be worked over. This was years ago, so maybe the new ones are are better?

I bought a new one from Snyder's on the day I got my first social security check! I think I paid about $400 for it. I put it on my car and it wouldn't work. I called Snyder's and they told me that they stored them on their side and the float was probably stuck. Told me to wrap on the side of it with a screwdriver handle. Never a problem since. That was about 9 years ago!

I bought one from Snyders and it was put on the day I received it with never a problem since. If you want quality it comes with a higher price tag. The same as Stipes shocks. You get what you pay for! If you want good clean oats they cost more than oats that have been through the horse one time !

I have three of them here, two won’t idle wort beans and the other lacks power at any speed. My original Zenith runs and idles fantastic. I have narrowed the problem to the top half on all three units.

Dave Slater, I have one that seems to run on the lean side. I have to run with the GAV opened farther than I would expect. I checked for vacuum leaks and found none. It runs fine with the GAV open ~1-1¼ open. Maybe try that.

One of these days I am going to rejet it to see if I can improve it.

These carburetors are made from repro parts, assembled and sold. They are not tested so that leaves room for the problems buyers experience.

Smile Re: New Manufactured Zenith Carburators

I bought a used repop Zenith carb a few years ago for -$100-. The seller said it had problems with it. I've not had any problems with it and in fact it is on my car now.

I purchased one of the AIR BALANCED ZENITH CARBS and ran it for the first 1000 miles of a road trip and it was getting about 4 miles to the gallon less than my original. I replaced it with the original and finished the trip. Put the new carb on the shelf when I returned from the trip about two years ago and kind of forgot about it. I will move it into my work area and start tuning....
Good Day!

I was running it with an air filter.

Interesting - keep us updated on what you find. Am assuming you are running an air filter?

Brattons IS working on a batch of the new carbs. We have found a small stockpile of new castings and are currently working on assembly and testing them. If you are interested call and get on the list as these will be gone soon.

If you’re running a modified engine IE bored different cam ect, then a re jet is a good thing.

Chuck. Basically stock engine with Snyder 5.5 head.

Update: I found the problem. The hole for the throttle shaft was way too BIG, sucking in air. Made the engine run super lean and would not idle. I had to install an oversize throttle shaft to cure the problem. And this is a new carb?

Anyway, something to check for. I wouldn't buy another.

Now that's funny......... I have never heard "buying a piece of $h**" described in such a nice way. One statement says it all. I love it, to bad this hobby is faced with this type of part

Another alternative is to purchase a rebuilt or have one rebuilt by Jim Bullock in Texas,. Flow tested jets, , tested, and does exceptionally nice work. The few people that have had issues report he makes things right quickly.
