SOURCE: 1986 truck will not idle until warm has a carb

Look on the side of the carb.There should be a couple of solenoids mounted.one of them is not working.Check for a blown fuse,and also take the solenoids out and clean,and reinstall.If this does not work,then find out which one is not working,and replace it.

SOURCE: carburetor idle mixture adjustment for lean burn chrysler engines

On a carbureted engine(the days of old) I had a method of my own
which always seemed to do really well.
Warm up the engine to operating temperature and make sure there is no
operation of the automatic choke.This should mean that the choke flap in the top of carb is standing vertically offering no resistance to airflow.
Hook up a tachometer if the car has'nt got one.
Note the idle speed in PARK.
Turn the fuel/air adjusting screw underneath carb's right or left sideI(NOT the idle speed set screw) IN and note the rpm as you do.If it raises a little,you are getting close.
Go ahead and turn that screw in all the way and lightly seat it(count the turns in from the highest idle reading),then back it out to the highest reading.NOW turn it in slowly until you see the RPM drop slightly.
Now back it out a little so you are at peak RPM again.
REPEAT this with the other side's fuel/air screw.
After you have gained this higher RPM (maybe), then set the idle speed control screw to desired RPM, and be sure to get in the car and while holding the brake,put the car in DRIVE to make sure the idle doesn't drop too low. don-ohio (:^)

How do I adjust air fuel mixture on 1986 Toyota Cressida straight 6 cylinder dohc


Unless your engine has a carburetor, you can't adjust your fuel mixture. That is done by your cars computer. It analyzes your exhaust emissions and adjusts your fuel/air ratio.
Your oxygen sensor(s) may need to be replaced, or there may be a computer glitch causing the problem.

Sputters at full throttle and wont idle


Run pressure test on your fuel injectors. Fuel pump might not be suppling enough fuel line pressure.

I have a 1986 GMC 1500 with a 5.0 and stock rochester carb. The truck will start but you must keep gassing it as it won't idle. It kicks off every time. Any suggestions on how to fix this cold natured


fast idle speed screw, works off the fast idle cam which the choke adjustment sets, it works together by linkages. This is the raised idle speed setting you need to keep a cold engine running. First you set the idle speed by the idle speed screw with engine at normal operating temperature. Then you set the linkage up so the cam is on a raised step, throttle will be held on that raised step. then you can turn the idle speed screw to get idle at about 1500-1800 rpm. Now when you start engine cold, choke will set the fast idle cam on that raised step- when engine starts and runs it should be running at your fast idle setting. That's how it supposed to work, you just have to get everything adjusted right. I hate carburetors, they never stay adjusted right. Considering their complexity and small mechanical parts, no wonder.

1986 Honda Accord DX - too high idle on cold start


1986-1989 Honda Accord with Carburetor have a very bad habit that is little known even by most mechanics but easily fixed at home. The vacuum port on the choke opener that is connected to the intake manifold and both vacuum ports on the fast idle unloader get plugged up with nasty hard carbon almost as hard as metal. When this happens the choke sticks closed and the idle sticks on fast idle when the engine is cold and nobody can figure out why. All you have to do is attach a small drill bit to the end of a flexible socket-driver extension and put it in a variable speed drill that will let you run it real slow and carefully drill out the vacuum ports that are plugged. After they are nice and clean use a vacuum pump tester to make sure the choke opener and fast idle unloader are working before putting it all back together. It's amazing how much better the car runs after cleaning out those ports.

Sounds like a fuel mixture/vacuum problem. Vacuum advance line on the distributor could be loose/leaking/collapsed.

Hello;
It sounds as if you have a couple of possible problems. First could be the fuel pump. If yoou disconnect the fuel line, put the line in a jar and crank the engine over, you should get a pint in 15 seconds or so. Also check the pressure, should have around 5 psi. Secondly, you may have a vacuum hose cracked, broken, or leaking. Check your hoses and also the carbureator for leaks.
Hope this helps;
Thanks;

Check for a vac. leak. First listen for a whistle or a high pitch sound if you have any fix them. You can get a can of carburetor cleaner and spray around the vac, hoses even the big one on the brake booster unit and the back of the master cly.
