choke
hey evry1, im new here and just trying to learn somethings.
Question:
Does the choke throttle also open the bottom throttle?
This is on a 84 351w /2 bbl.or
Is there a seperate screw setting?
I have the round black cover for the choke. thanks.:-X12

There throttle butterflies & a choke butterfly.
The choke butterfly (top of carb) shuts air off to the intake (thus called Choking).
The bottom butterflies are the throttle plates which open up and allow fuel & air into the intake manifold.
How this works is :
When you first press your foot on the accelerator pedal you are allowing the upper butterflies (choke) to close and with a few pushes of the pedal squirt gasoline into the engine.
This is why the exhaust comes out black (rich condition).
As the engine & choke return spring(coil spring inside the black housing)warms up the choke comes off.

I have the same engine and latley it has become more and more hard to fire up. Could it be one of these chokes causing the problem. It turns over great but takes a while to start, sometimes have to start two or three times to keep running.

Hey while we are on chokes I have question. The wire that runs from the choke housing that supplies the power to warm up the spring, where does it connect to. I am told that it hooks up to the alternator back called the stator i believe. Is this true?

I just had my carb rebuilt. When I removed the carb, it had no wires. When I got it back, there were 2 wires coming from it. I asked the carberatur guy where they go.
The wire on the passenger side of the carb needs to go to a power source that is hot when the key is turned on. He suggested the red lead going to the wiper motor. (I don't think the original carb on my 84 had an electric choke)
He strongly discouraged connecting to the coil or the alternator in any way. He said that is ok on Chevys, but not on Ford. He didn't go into detail why.
I made the connection yesterday, and she's running like a champ again.

I forgot to mention the second wire. It is connected over near the throttle linkage. He said this one is for the A/C. It connects to the compressor so when the A/C is on, it will idle a little faster.

choke
The ORIGINAL ford choke set-up hooks to the stator terminal on the back of the alternator with a white/black wire. The original choke housing has one terminal.
I believe Rick Ford has an aftermarket choke set-up, since his has 2 terminals. The aftermarket set-up requires a full switched 12 volts from the ignition switch or somewhere else convienent. I believe the other terminal is ground. The factory choke housing is grounded through the carb housing.
Some manufacturers who don't use the alternator hook-up, run the voltage for the choke through a special oil pressure switch.
All of these strange ways to hook up the choke is so it doesn't open the choke if the key is on, but the engine is not running.
