Choke dont work

if too rich adjust choke leaner
if too lean, adjust choke righer.

from 1920 to about 1988 , usa, 70 years we did this.
no more. well we do, but most dont now.
i still have 1 twin carb motor cycle and one single carb VW 1968.
both restored.
also the chock heater must work and the choke spring not old.
the old bi-metal spring that is old become lazy,/crazy. kick it to the curb for best experiences.
if water heated choke the water actually must flow here.
if not, it will fail.
there are 3 common types.
electric, needs 12v.
water, needs 180F hot water actual flow.
and exhaust choke stove heater. (a small horror this, dont ask)
there are others, but would need carb name and p/n

need to clean the idle jet out in the carb. you need to take the carb float chamber apart and you will see 2 copper jets. unscrew one jet at a time and clean them out. screw back firm not to tight. wile open clean the filter out of the main fuel line if its black replace with new one or leave to soak in some white vinegar and brush with a old tooth brush put new seal on float chamber and put back on engine. see if its fine then it should be.

What kind of carb does the 76 c10 4x4 come with need to adjust

mcdevito75 here, The fast idle is needed when the engine is cold to make the air and fuel mixture rich to keep the engine running while cold, the carb. choke doew this with a bi-metalic spring in that balck round box on the side of the carb, a screw also hepls keep the choke closed until warm up, this screw can be adjusted tpo control how tight it holds the choke cloesed, here"s how to adjust this screw to slow fast idle speed, Locate on the carb, where the gas pedal connects, have a friend operate the gas pedal with the engine off, once you locate the linkage, you"ll also see 2 screws with springs around them, 1 is for fast idle the other for regular idle, you want the fast idle screw, notice this screw will lay against and Half moon shaped tab, while the other screw lays against a shaft, you need the screw that lays against the half moon shaped tab. Start the engine and step on the gas pedal slightly and relaease, at the screw that lays against this half moon, simply turn it counter clockwise or toward you just 1 2 or 3 turns very slowly, you'll hear the fast idle come down but you don"t want the fast idle to low, listen to the engine very carefully, slow it down just a bit, it should still race though but not out of control. Of course for a full carb, adjustment the shop should handle that., but this info will help.

How do i adjust carb on 84 cj 7 it is running rich and has some black smoke

The first thing to do is make sure that the problem is not the choke butterfly. Make sure it is opening all the way because a partially open choke can mimic improper idle screw adjustment, letting it run rich. If the choke is good then you will find the idle adjustment screws at the front of your carb. They are under the float bowl almost touching the intake manifold. This is easy to screw up so be careful and take your time. Turn both screws equally, the same way and the same amount. Use 1/4 turns and try running the engine after each 1/4 turn. Rev the engine up 2 or 3 times and let it come back to idle.If it stalls then turn it up a bit so it doesn't. You may have to adjust your RPM if it idles to low at the throttle linkage. There will be a screw stop there for that purpose, turn it in to speed up and out to slow down. It's a trial and error exercise even for professionals so take your time. Hope this helps.

Carb is acting weird cant seem to adjust

That is the choke adjustment,have you checked your timing on the motor and check and see if the vacum pod on the distributer is working. also check your vacum lines for any tears or cracks in them.

I have a 1981 GMCvandura 25 with a 350 4bbl carb. the choke.

Its all in the idle screws, if there bad you will be chasing them every time you drive it, also the choke spring inside could be bad, if you have a that style. screw the idle in on both sides all the way in, then back out 2 and a half turns, this should be where you will run the best. adjust as needed, but that is the standard. i also run sea foam through the carb, alot better then any cleaner on the market. usr it in your fuel or try to put it in the carb, i have uesd the vacume lines to do this, but you will also have to keep the car at high idle when doing this, it will clean all of the junk and carbon out of the entire motor.

if you need more help, please be clear or the carb, and hat you have done and not done already'
