Quadrajet Choke Adjustment

[@MrNodnarb123]

Working on adjusting mine on my 79 Malibu. This was a great visual aid to give me an idea. Thank you.

[@Ami8driver]

My choke was too closed. Your video helped me a lot to open it a little bit for cold starting. Now my 454 gets enough air for running cold, without black smoke! Greetings from Spain! 😎

[@BlacktoppPerformance]

So very glad it was helpful. Thank you!

[@boerenbrommer]

What were your symptoms?

[@ThunderAppeal]

@@boerenbrommer The syptoms is an American car in some uropeeyon shythole. Thats the problem.

Great video worthy of thumbs up and subscription I watched about half of it, spent 2 minutes adjusting my choke and now it starts perfectly PROBLEM FIXED! Thank you

[@BlacktoppPerformance]

Love to year that! Thank you

[@tragenkismet]

Thank you for this fabulous informative video which meant my 79 Trans Am choke was fixed in record time! So grateful.

[@BlacktoppPerformance]

Very glad to hear it helped

[@formula721]

Thank you for posting this video. It helped me a lot setting up my fast idle screw and choke. Now my Grand Prix starts right up on cold mornings.

[@gcalvin8889]

Just watched 6 different videos about this.... yours was the only one that was helpful thanks

Very glad it was a help. Thank you

Thank you! I’m messing with a 77 Monte.

Thanks for this informative vid

[@davidpotter7484]

That looks like the wrong coil for that carb, the hook is upside down. I have quite a few different ones. I found the correct part number for my 17080213 carb, I bought 7 extra NOS choke coils for it off of ebay as spares.

[@rayladd856]

VERY good info to know, i did not know that was how to adjust it, thank you

[@BlacktoppPerformance]

You're welcome, hope it helped

[@TruckThisGarage]

What is that diaphragm thing for with the rubber hose that uses vaccum?

[@BlacktoppPerformance]

@@TruckThisGarage It initially opens the choke a little upon starting, helps to start up until the spring inside the choke housing has a chance to warm up and expands to open the choke valve the rest of the way.

Thank you

I have a 84 Pontiac Pariesienne has new carburetor need set my choke, hopefully it works on mine, opened choke started up, closed didn't start, now it overheating after warmed up a few minutes

[@BlacktoppPerformance]

Your's should be electric choke

[@savagebrutality1]

@@BlacktoppPerformance It is the choke was still closing, it's a bitch to adjust

Thank you work on my 74

Very happy it helped

Good morning. Thank you for your video. I have owned a 1975 Corvette for two years. Until recently I started the car easily without problem and now I have the idle which remains at the fast speed at 1500 rpm with a tendency to increase. I'm in trouble because the car is stored in a fairly small box in the basement and I can't stay there with the engine running. What do you think I should check first? Thanks for reading me. Please excuse my language, I am French and I use Google translate.

[@BlacktoppPerformance]

First, check all linkages and make sure nothing is sticking or gummed up. Then check for dried out gaskets/seals, replace as needed. Me, I would drive it and see if it clears up. Hey, if you see a 1973 Black & White Dodge Charger over there in France, watch out! Sold it a few years back, and it's Big Block will eat Corvettes lol...Hope this helps ya

[@user-wb2ss6nz6i]

@@BlacktoppPerformance Thank you for your reply. I'll look at what you recommend. Yes, I'm also thinking about the vacuum line and I noticed that when heating, the motor gives off a smell of burnt rubber. On the other hand, driving the car, I am afraid of breaking the engine because of the temperature. In any case, thank you and I will watch out for the black Corvette eater... Best regards.🙂

[@edgarherrera5085]

Ok so when you do the adjustment choke tension do you do it when you already have choke plate closed or while it's still open (cold engine). Thanks

[@BlacktoppPerformance]

The choke plate should be closed [cold]

[@edgarherrera5085]

@BlacktoppPerformance darn, ok. I just installed a new one on my 78 Cadillac with the 425 and I did it when it was open (cold engine). Would I need to remove it, have choke plate closed and reinstall it...(of course on cold engine)

[@BlacktoppPerformance]

@edgarherrera5085 yea the choke plate will be open only on a warm engine, on a cold engine plate must be closed. That's when you want to adjust it

[@edgarherrera5085]

@BlacktoppPerformance thank you sir. Car still runs fine after its warmed up, it's only at start up and I have already driven the car today after the install. I'll let car sit overnight and make sure choke plate is closed, loosen screws and adjust. Think it's shutting to tight, because on your video it's partly open after you adjusted it. Thanks for the reply. Hope this resolves my cold start issues.

[@BlacktoppPerformance]

@edgarherrera5085 yea on my car, it likes to be opened about the size of a dimes thickness. Sounds like your on the right track

[@jorgelimon2608]

Una pregunta, de donde se toma la corriente que lleva ?

[@burninwordz0078]

No es electrica

[@ahmadaldahoud1719]

Hi there , I want to ask my car some time have a stuck padel , I checked all the linkage it's ok , but I am thinking fast idel is stuck as I can't get the get idel speed screw to rest on the leaver, what you think.

[@BlacktoppPerformance]

What kind of car is it? What carburetor is it?

[@ahmadaldahoud1719]

@@BlacktoppPerformance Camaro 78 z28 with 350 and Rochester quadrajit

[@BlacktoppPerformance]

Sounds like you're fast idle is sticking, perhaps the linkage or lever has been bent or just has debris such as grime,dirt or grease not allowing it to move properly. The fact that you're curb idle screw will not rest on the lever tells me it's something to do with your fast idle linkage. I would spray it with carburetor spray and clean it very well as your manually working the linkage. Hope that helps

[@BlacktoppPerformance]

Not sure if you've seen this video I did on fast idle adjustment but maybe it can help you sir....kzbin.info/www/bejne/Z3PEn56QhNWYrs0si=o7aYDDpewpJYJU2w

[@ton-locc8069]

My choke is different doesn't have that spring box any help???

[@BlacktoppPerformance]

Well, since you don't have a hot air choke, I'm just gonna guess you have a divorced choke. Here is a link to a good video that might help you....kzbin.info/www/bejne/eaSYe2Bvj6p9grssi=JeDx6H-gDaOtGFdm

[@ton-locc8069]

Ok thanks for the video

[@waynegreen6789]

Do you set it dime lenght cold or warm

[@BlacktoppPerformance]

When it's cold, it would be best if engine hasn't ran for a few hours

[@waynegreen6789]

@@BlacktoppPerformance thank you

[@BBee392]

Too bad he didn’t start it up. Then we could of been the judge of the choke video. Just have to take his word for it. I wondered if it even ran.

[@BlacktoppPerformance]

Lol, obviously, you didn't watch the video before this one where I started it. I also answered your question in the first 30 seconds in this video. Or you could just take my word for it. Have a beautiful day sir
