Advice trouble shooting my carb (stalling)

[Sumit]

So embarrassingly I don't know much about carbs.

Its burning rich but the main issue is she stalls out when accelerating from a stop. Its almost like I can find the flat spot where chokes with the gas pedal. Sometimes It seems like if I give her more gas quicker she gets past the spot (but sometimes still stalls). Others if I start off slow and let her build up on her own through the intersection and then give her gas, the "spot" won't effect her. But like I say its hit and miss.

Does this seem like she could be flooding herself?

Thanks in advance for any advice.

What kind of carb? Make and Model would help.

First thing is to check the fuel bowl level.

The flat spot/stall on acceleration sounds like it could be an accelerator pump problem. The running rich is a separate problem. Chuck

I agree with Chuck

Accelerator pump not pumping

Is your carb a Motorcraft 2100 series? If so I concur with the others who responded that your accelerator pump diaphragm has failed and is causing flat spot/stalling. If it is running rich your power valve is most likely leaking (very common).Power valves typically fail due to back fires through intake causing a rupture. This is a very simple carb rebuild as far as they go.

Yeah I agree it's the accelerator pump. I've had to replace a few and it's not a big deal.

Hey guys thanks for the advice. I looked into it more and it totally sounds like my problem. I will be replacing it as soon as possible. You guys are the best.

Don't forget that anything with old rubber-like materials (e.g. elastomer) may degrade in ethanol-rich fuels. The accelerator pump uses a diaphragm (IIRC) that may have deteriorated.
