Carter YF 3211s issues

[Isaiah92260]

Hey fellas, I have a hard time not messing with my truck. Ha
Anyways my Rochester 1bbl was working fine, but I was hearing a lot of good things about a Carter YF. So I finally found one and had it rebuilt by a local carb rebuilder near me in El Monte.

The issue I’m having with the Carter is that when I start the truck up, it idles fine, even runs fine. It’s an automatic choke but my truck is set for a Manuel choke so I installed a universal Manuel choke which works fine, but I noticed that at a cold start up, the choke doesn’t let the truck start, it’s better to pump some gas, start her up and hold the pedal a bit till it idles on its own. Also once the truck warms up and I start driving for about 5 minuets, the truck starts to run really rough and then stalls on me which is my main problem.

After it stalls on me, I will let it sit for a couple minutes, and then it’ll start right up, but again once I take off, it stalls on me again.
It,ll do that over and over again.

But as soon as I pull back into my garage and let the truck idle, it keeps running.

Strange right?

Finally after letting it idle for a bit, it started to run rough again so I finally shut it off, and opened up the carburetor. I found online that the float level is 1/2”, float drop is 1 1/4”, and the meeting rod plate should be touch the metering arm base. I checked all those and they were spot on.

For a second I was thinking maybe the carb was flooding

So now I am stumped on what it could be.

My Rochester never did this. Reason why I switched them out is because the Carter is supposed to be a better carb, little more power and MPG. The pedal travel on the Carter is a lot more on the foot which was nice.

I have a 1961 235.
And I have a Carter YF. 3211s.
If anyone has any experience whith these 235 Carters and can help me out please let me know thank you.
