engine stalls when step on accelerator
 

1933 model B
Now that I finally got my car running again, idles fine, but engine stalls when step on accelerator. Could it be a fuel pump problem?

Re: engine stalls when step on accelerator
 

I doubt it is the fuel pump because the carburator should be full of gas when you step on the accelerator. The stock carburetor doesn't have an accelerator pump so it is not that. My guess is that it is in the carburetor, can you borrow another one you know works? By the way you should add your general location to your profile.

Do you have your mixture turned in too far on the choke cable. try turning it out a turn or so and see if it helps. I have seen bad condensors cause the same issue.

Re: engine stalls when step on accelerator
 

Have you tried turning the choke counter clockwise a little
to richen the mixture?


Never mind Michael beat me to it.

Re: engine stalls when step on accelerator
 

where is the adjustment on the choke cable?

Re: engine stalls when step on accelerator
 

Turn the knob that you use to pull the choke.

I never knew this had that function.
Note..I have a stromberg 35 carb.

Re: engine stalls when step on accelerator
 

Your carb doesn't look like this?

Re: engine stalls when step on accelerator
 

no, my carb is a stromberg 97 carb

Re: engine stalls when step on accelerator
 

stromberg 97 carb installed with downdraft attachment

Whole entire different animal. Look into the accelerator pump.

Probably easier (and cheaper) to fix, though.:)

Re: engine stalls when step on accelerator
 

That changes the whole game. You carb should have an accelerator pump. With the car not running press on the gas and see if you get a squirt of gas into the engine. If you don't, that is probably your problem. Probably time to rebuild the carburetor.

how do I reach uncle max

Re: engine stalls when step on accelerator
 

IS it me OR I would like to see JUST how a Stromberg 97 is working on a 33 4cyl (Model B) from what should be an "updraft" single barrel carburetor, right?

Re: engine stalls when step on accelerator
 

Just wondering, is a 97 carb a bit much for a stock 4 banger?

Re: engine stalls when step on accelerator
 

Lots of folks run either a Stromberg 97 or Holley 94 style carb - seems to work really well!

Re: engine stalls when step on accelerator
 

The Stromberg 81 is the preferred 4 banger carb, but they are hard to find and pricey

Re: engine stalls when step on accelerator
 

Charlie, you are a genius!
I swapped out my carb for another Stromberg I have and the can ran great.
Thanks so much.
I will send my problem carb to uncle max for a rebuild.

Re: engine stalls when step on accelerator
 

Thanks everyone for your help. This is a great group of knowledgeable people.

Re: engine stalls when step on accelerator
 

You'll get one of these from Max. Runs perfect out of the box

Re: engine stalls when step on accelerator
 

I installed a new downdraft intake with the stromberg on top. This supposedly gave me 10 % more power? I could always go back to the updaft and the zenith carb if I have to.
