Some more questions

Hi guys,


Getting used to the car a bit; switched tires on sunday, checking lights and stuff i found 2 parts im not sure what they do. Beneath the lights switch, is that the choke?

And left to the emergency brake, those 2 handles? Front seat passenger has the same handles.

Re: Some more questions

Knobs, 2 for each side are your vents. Pull to open, push to close.

I guess im rather save than sorry


And about choke? Car runs a 750 dp 4779-2 carb. Google said all of those come with a manual choke.

Re: Some more questions

My 72 doesn’t have that. Not sure what that is.

I've never needed or used a choke on a double pumper...or any other Holley. I simply pump the gas pedal twice and turn the key. And if it doesn't start, repeat the process. If you have a choke butterfly plate, wire it open.

Re: Some more questions

Your first picture, that does not look like a pull lever for a manual choke. A choke pull lever should / would look like a headlight knob or like your vent knobs in picture #2, but it would be an aftermarket part (Generic looking, maybe on a sheetmetal bracket.) Picture #1 looks like an AC vent.

Re: Some more questions

From the top of picture 1, 1st square sliding knob is windshields wipers, 2nd round shiny knob is headlight switch. 3rd bid round thing is the Astro air vent or a/c vent if you had a/c. I see no choke controls in either of your photos. If you can pull the air cleaner off and snap some pictures of the right side of the carb, we can tell what type of choke you have. Some carbs have no choke, some have a cable activated choke, and some are electrically operated.

The second picture shows what is called the Astro ventilation controls. They open the foot air vent and the other makes the air come from the dash vent. The air you get through the vents comes from the cowl area in front of the windshield when you car is moving. When you drive the car, pull or push on them and you will get the idea.

You'll need to check to see if this is hooked up. It maybe wired open or held open in some way.

Here's a list of various choke cables so you can see what they look like. If you don't have one you can install one. But many of us don't use the choke cable, we sit in the seat and keep the car running with our foot until it warms up. In cooler temperatures, a choke may do you some good.https://www.summitracing.com/search/...e/choke-cables

Re: Some more questions

I have the same carb on my 69 with a 396 engine. You can put an.electric choke on that carb. It is what I would recommend and then it is automatic. Don't have to think about it. It is an easy install. Many moons ago when I bought my car it did not have a choke on my 750 double pumper. Can't remember where I bought it but most likely Summit Racing. Will just have to run a wire to a 12 volt source that is key activated.
