1951 Ford 6 Cyl Carburetor

Anyone running one of these carbs on a 226-6cyl flathead? Anyone using this carburetor with success? I have had several and not a lot of success, stumbles on acceleration but runs well under power.
Thanks, Steve

I have run a stock carburetor on a 1950 Ford sedan with H series six cylinder. I cleaned up the parts, made sure all the passages were clean, put a kit in it, verified accelerator pump worked, and it ran well for me.

I bought a kit for my stock carb on my '51 226 cu in H and it runs well. No stumble when at temp, but likes a lot of choke. It DOES take forever to warm up. Does yours have a working heat riser in the exhaust manifold? The flat wound spring is rusted off the manifold flapper on mine so as a test I hooked up a light coil spring for a few minutes and it made a huge difference. Check that on yours since various carbs made no difference for you. Just a thought.

The rebuilt stock carb on my 226 G-series six ran well although I felt it was under carburetted for the engine and considered modifying the manifold to fit a 94 of 97 on it to improve the CFM flow to see how that would improve performance. Never happened before I sold the car

My Dads '50 with the 6 ran perfect it's whole life. Completely stock until he put a split manifold on it. Never an issue, started perfect, ran perfect until a piston top detached from the skirts...after 60 years. We figured it was because he would pull 2 trailers to Cushman events. After a while, it was just too much.



Stumbles on acceleration usually lead to a few things, accelerator pump, timing or vacuum leak.

Was that a split exhaust manifold? Been thinking of doing that..
I have rebuilt several carbs, checked timing, looked for vac leaks.
I am baffled...

Yes, it's still on the car. Good luck finding one. Most guys just use a stock manifold and bore a 2nd hole, then weld in another pipe. It's not a true "split" design, but it works.
When you say "stumble", is it a momentary hesitation, or does it stumble through the entire acceleration time frame? If only momentary, I would look as closely as possible at the accelerator pump. Make sure it starts pushing fuel as soon as the throttle moves. Many times there is a delay in the linkage that will cause it. I assume you can see fuel being pushed out when looking down the throat (obviously not when it's running)?
