Manual Choke Ignorance!

[savatreatabvr]

Yeah, a manual choke is pretty much self explanatory but for some reason mine is fighting me! There's only a fraction of an inch between stumbling, the sweet spot and stumbling again so I'm wondering if something else is wrong with the Quadrajet!

Your q-jet may be fighting you, or your fighting yourself.(?)

I'm not going through multiple threads on your carburetor to find out what has already been suggested. As I mentioned in them, you'll have to do a little work to get the wrong kit to work. No kit instructions say "twist cable through this hole", I do believe there is supposed to be a linkage on the vacuum can, so I can't tell you what else is fubar.

Hopefully in a couple of weeks I'll have my truck back, and can post you a pic.

Describe your starting procedure.

And, what's the temperature in phoenix now?

[savatreatabvr]

Temp is around 70 day and 42 night, I pump it 3 or 4 times pull the choke until it starts and then slide the lever in and out until I find a sweet spot, if I find one!

I'm not a shade tree mechanic or can afford to pay one to work on my truck for me so that's why I post on this forum, I apologize if I'm asking the same things in different threads but if my questions were answered then I wouldn't still be having problems now would I? I'm a single dad trying to keep a roof over our heads and food on the table so I obviously can't go without my truck so that's why I reach out on this forum for help, I can do without rude comments from someone who doesn't like multiple threads!

I'm sorry for coming off rude, but your making fixing the carb more difficult by multiple postings on the same subject. As it stands now, your the only one who knows what has been done. Several folks have posted tips and things to try, and we don't know what you have tried. Try bumping up one of your older threads so people can see what has been suggested and tried, or linking them in this thread. I am trying to help.

I consider myself as a shade tree mechanic- out of necessity. I too can't afford to pay someone to do my work, or call a wrecker if I'm stranded on the side of the road.

I think I asked in another thread but if I didn't, does the fast-idle work?

[C-10 simplex]

Actually, that is a good point: With the manual setup installed, does the fast and mid idle still function?

Irregardless of the that, a fraction of an inch between smooth and rough does sound right---i adjusted my choke pulloff only a hair and it made a big difference.

i would almost bet money that with those temps you probably don't even need to use the choke? Also, i think you only need 1 pump if the engine is cold unless it's been sitting for a few days.

So after it's all warmed up and you open the choke all the way, does it run smooth?

P.S. i noticed that the secondary air flap control is disconnected. This is not important now though.

The fast idle still works in means of I turn the screw and the idle raises but I'm not sure if it's adjusted correctly.

You DO need the secondary link!!!!! The choke break dampens the secondary flap opening to control the flap from opening too quickly and causing a bog when they open.
That choke arrangement gives a LOT of choke change for a very small change on the cable. I don't see a fast idle cam at all.
Get a Q Jet book and READ it!!!!!
Rochester Carburetors by Doug Roe and the one by Cliff Ruggles and very good.
You have too many problems to solve here!!!!!!!!
Properly tuned, Q Jets will beat ANY carb on a normal street app!!

Are we talking the right screw? Fast idle screw is behind where you've got the choke cable connected. On mine, you could almost feel it drop in before you cranked the truck. Hold throttle to the floor for a second when you choke it. (before you hit the key). When it starts, idle should be 1200-1500 rpm. (+/-)
When it's warm, you should be able to blip the throttle to kick it down to your normal idle.

Hotrodrobert mentioned get the books. You can even check them out of the local library. Tons of information on general operation and troubleshooting.

this is why i dont deal with quadrabogs...nothing but issues and probs

[motornut]

make your self a build thread throw up a bunch of pics of the engine etc for some back ground info pls

show it from the top pushed in and pulled out how far it travels
later when it's setup trim back the wire so when pulled it goes to the sweet spot

[donut]

All the time?

If so, you've got deeper issues. Possible clogged passages, too lean/rich, vacuum leaks...
The carb should run close to primo before you start monkeying around with the choke. (IMO.)

Then at least you have a baseline to start from.

I have run without a choke below 0, it's just a pain. Lots of folks run for years without a functioning choke.
