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! 😎
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
@@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.
Thanks man I raised my idle RPM to 900 from 800 and actually burned the gas puddles in the quadrajet and passed smog well below instead of above max levels after replacing the vac lines and bad spark plug cable eaten by rats. When I went to shut off later she was dieseling and I realized I was idling high and stuck in choke with temps rising fast. I released the auto choke without loosening the screws by toggling the lower lock and it clicked unlocked and fully closed. Saved me hours and a possible fire. 🎉
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.
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
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.
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
@@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.🙂
In case automatic choke stuck on with the quadrajet, it merely requires a little French finger loving to release so it will idle down and close both flaps properly again.
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.
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
Not sure if you've seen this video I did on fast idle adjustment but maybe it can help you sir....ua-cam.com/video/1BankZOpexk/v-deo.htmlsi=o7aYDDpewpJYJU2w
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....ua-cam.com/video/Cs5J-9ZEJLY/v-deo.htmlsi=JeDx6H-gDaOtGFdm
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
@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 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.

So very glad it was helpful. Thank you!
What were your symptoms?

Thats the problem.

Love to year that! Thank you
Working on adjusting mine on my 79 Malibu. This was a great visual aid to give me an idea. Thank you.
Thank you for this fabulous informative video which meant my 79 Trans Am choke was fixed in record time! So grateful.
Very glad to hear it helped
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.
Just watched 6 different videos about this.... yours was the only one that was helpful thanks
Very glad it was a help. Thank you
VERY good info to know, i did not know that was how to adjust it, thank you
You're welcome, hope it helped
What is that diaphragm thing for with the rubber hose that uses vaccum?

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

Ok thanks for the video
Do you set it dime lenght cold or warm
When it's cold, it would be best if engine hasn't ran for a few hours
@@BlacktoppPerformance thank you
Una pregunta, de donde se toma la corriente que lleva ?
No es electrica
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.
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
I made a video for divorce choke
Sweet, I'll check it out man

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
The choke plate should be closed [cold]
@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)
@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 yea on my car, it likes to be opened about the size of a dimes thickness. Sounds like your on the right track
