In general there are fewer ways to adjust the newer carbs than the vintage carbs of the past. Often the vacuum at low idle is the problem and you should check a vacuum port on the intake with a Vacuum gauge.

Sometimes an EGR valve does not shut completely and the engine struggles at idle. If you find that vacuum is adequate, you can adjust the air mixture screws to provide the highest vacuum reading and then crank them in until the vacuum falls less than 1 inch.

It might be beneficial to run the engine and spray a water mist from a hand powered spray bottle around the seams of the intake and carburetor. Also spray any vacuum solenoids or lines. You will notice a change in RPM if there is a leak.

You may have a fuelpump problem A clogged fuel filter or low pressure can affect how the car idles.

Please rate my info.

Hmm...many things got involve there...if its a non computer controlled carb....it maybe caused by faulty auto choke,EGR valves,vacuum leak or blocked,dirty air filter,dirty spark plug,valve stem seals loose,fuel pump,fuel filter or just simply the carb needs a carb spray...If it is a computer controlled...you need to check EGR valves,vacuum,temperature sensor,thermostat,CO2 sensor,auto choke,spark plugs,air filter and simple as carburetor cleaner..

How do you adjust idle speed 1991 johnson 100 hp


not important, what's important is that they are absolutely clean, including the four brass high speed jets located in the bottom center portion of the carburetor.

That model engine's carburetors has fixed jets, BUT if the slow speed jets are adjustable, earlier model carburetors have been installed. If so...................

The four adjustable needle valves control the flow of fuel in relation to the set air flow, adjusted as follows (if needed).

(Dual Carb V/4 With 4 (2 each carb) Slow Speed Adjustable N/Valves)
(J. Reeves)

The adjustment procedure of the carburetor slow speed needle valves follows. NOTE... if the needle valves turn too freely, replace the nylon bearing retainer (the nylon item at the front of the carb that the needle valve goes through first) with the newer type RED retainer #315232. If your engine has that weird linkage that connects all four of those needle valves, the newer RED retainers will enable you to discard that linkage. The RED retainers make it impossible for the needle valves to vibrate out of adjustment.

(Carburetor Adjustment - 2 Slow Speed Adjustable Needle Valves, each carburetor)

Initial setting is: All (4) Slow speed valves = seat gently, then open 1-1/2 turns.

Facing the carburetors, start with the top left needle valve, then the top right valve, then the bottom let valve, then the bottom right valve. It may be necessary to redo these steps to get the adjustments ideally set

Start engine and set the rpms to where it just stays running. In segments of 1/8 turns, start to turn the S/S needle valve in. Wait a few seconds for the engine to respond. As you turn the valve in, the rpms will increase. Lower the rpms again to where the engine will just stay running.

Eventually you'll hit the point where the engine wants to die out or it will spit back (sounds like a mild backfire). At that point, back out the valve 1/4 turn. Within that 1/4 turn, you'll find the smoothest slow speed setting.

Do not attempt to gradually adjust all four of the valves at the same time. Do one at a time until you hit the above response (die out or spit back), then go on to the next valve.

When you have finished the above adjustment, you will have no reason to move them again unless the carburetor fouls/gums up from sitting, in which case you would be required to remove, clean, and rebuild the carburetor anyway.

Carburator and idle problem


Believe it or not you just said the solution to your own problem manufacturers specs requires for any adjustments to engine idle or other carburator adjustments to be preformed while the engine is idling and at normal operating temp in plain english let the car warm up then make your idle and mixture adjustments if this doesnt solve it i would check the auto choke and make sure it is opening at normal operating temp hope this helps good luck

I got a problem on a caburaror on aselerate truck 87 dodge


Idles, automatic chokes, and kick down idles must be adjusted. You cannot just install a carburetor rebuilt or new without making idle and linkage adjustments to match the engine requirements. Does it have an idle solenoid adjustment and kick down adjustment, double barreled?. Did you get new springs for linkage? Have a mechanic make the adjustments. Find an older mechanic that knows carburetors.

Carburetor diagrams deni pd24jh


Did you adjust the idle mixture screws ? Is this a two or four barrel carburetor and what make carb. Carter , Holley, Quadrajet etc.. What make vehicle is it ? Normally the idle mixture screws should be opened 1 and a half turns to two turns . counterclockwise from fully seated . Then you can set the idle screw to what the idle should be 600 rpm to 750 in drive . Most cars have a decal somewhere under the hood telling all these things !

1969 ford mustang revs up on start then immediately dies.


Sounds like carburetor problems. Does the choke plate open enough to keep engine running? Or the fuel level in the carburetor may be too low-adjust floats for that. Check idle speed settings -idle speed screw. Idle mixture setting-the idle mixture needle.
If still no help, buy a carburetor rebuild kit for it-not expensive, will have all new gaskets and the parts that normally wear in the carb. Instruction sheet and a numbered dismantling sequence will be included in the kit. If you have never taken a carb. apart, let someone who has do the rebuild, an awful lot of tiny parts to keep track of, and you cannot let mix-ups occur. One wrong jet in the wrong place, and you will have to do it over. One check ball that wasn't placed, and you have to do it over. Mechanics are glad that carburetor days are over-fuel injection is more reliable, with about a hundred fewer parts to check on.

I am looking the idle adjustment screw on my 1971 350 cu. in. El Camino Carburator


Remove the air cleaner to access the carburetor.
Note the right side of the carburetor where the accelerator cable is connected.
The cable is connected to the accelerator cam which is stopped by the idle set screw.
The Idle adjustment screw head is pushing down on a spring, which should help Identify the correct adjustment screw.
Be careful not to adjust the smaller mixture screws, unless you have a vacuum gage.
If your Idle is too high you may get after run or knocking. I would set the timing then adjust the idle afterwards.
I hope this helps out since I do not know if the carburetor is stock or not.
