ok well i just swapped out my intake from the stock manifold to a non (egr) manifold and ordered a new carb. well i got it in and its a manual instead of an electric, is there any way i can use this or do i have to send it back ?

 

You can install a manual choke cable or you can install an electric choke kit. If your carb is tuned right, you really don't need a choke here in central Alabama.

 

, well ima go ahead and install it but do you mind if i ask what the choke does and why its important ? im new to v8 other cars a focus lol

 

how will not having a choke affect my regular driving ?

 

You need the choke for cold starting and proper operation until the engine warms up. Even in central Alabama, you should have it operating.

Exactly what carb did you get?

 

the edelbrock preformer series 600

 

Get an Edelbrock electric choke kit for it.

 

once the motor warms up the choke does absolutely nothing. the choke serves to create more vacuum below the blades to help the fuel atomize in cold/low vacuum situations because an engine will not run on liquid. right 57kid.

 

No, the choke serves to create more vacuum in the booster venturi to pull more fuel through the metering system than you would normally get with just the flow through the boosters. This is needed because the liquid doesn't vaporize as well in a cold engine, so more fuel is needed to get enough vaporized to let the engine run (liquid doesn't burn, even liquid gasoline). This also produces more unburnt fuel, which means reduced fuel economy and increased air pollution. This is further compounded in a cold wet intake system by fuel hitting the cold surfaces of the intake and condensing fuel out of the air, hence the "early fuel evaporation" system which warms up the bottom of the intake manifold by passing exhaust gases through a channel below the plenum.

Fuel injection, on the other hand, takes the liquid from a high pressure to a much lower pressure, which has the effect of vaporizing the fuel more rapidly. It still needs to be richer when the engine is cold, but not as much, and it's more controlled. However, wet intake systems like TBI still need the EFE system to prevent pooling.

If you can start your car cold without a choke without problems and without repeated pumping of the accelerator pedal, your engine is running much too rich when warmed up. This is true even if the outside air temp is 80 degrees.

 

right like i said once the motor warms up, and there is sufficient airflow through the boosters to atomize the fuel flow the choke doesn't have a function.

 

Except the boosters don't atomize (or even vaporize) the fuel. Their only function is to create a low pressure to pull fuel through the metering system from the fuel bowl and into the air stream.

 

so then o great and powerful one what does atomize the fuel?

 

I always thought the choke flap restricted air flow, as cold air is denser air, to avoid a lean condition on start/warm-up.
