Red-Lite Misery

After I've done a nice run outside of town, I'm getting hesitation/stalling while waiting for lite-change, they're getting longer now. Would the Model B Zenith be worth it? This is my second Model A Zenith now, and was wondering if I should consider.
Thanks
 
Fix what you have. If it is the carburetor, it should be an easy fix. Its a simple carburetor. Clean it, a tag wire thru the passages followed with a can of Deep Creep spray and some air should work. Set the float level. Adjust the idle mixture and speed, set the GAV at 1/4-3/4 turn out and it should be good to go.

First make sure there is not an air leak and the ignition system is good.
 
What’s the ambient temperature? It sounds the the beginnings of vapor lock. Try insulating the gas line and adding some marvel mystery oil to the gas. I ended up with an isolation spacer between the carb and manifold. I also built an aluminum deflector that not only shields the carb from the engine, but directs air from the fan. My car doesn’t “hesitate” after a run at the traffic lite anymore. If you shoot your carb in different places with a temp gun, you’ll be surprised how hot the carb gets.

I had that problem. Sediment in the float bowl was causing it.

why I put a magnet in all of my float bowls.

So after a nice long drive everything is warmed up and adjusted for cruising. I would try opening the GAV and maybe retarding the timing a little. Can you get it to die parked in your driveway? after its warmed up? I would adjust your carburetor idle speed and idle air
 
That shield looks interesting. Do what ya gotta do to keep driving is what I always say. So, good for you!
