Have a qualified mechanic rebuild your original carburator and reinstall it with all the original vaccum hoses and controls functioning properly.

Someone smarter than you and I, designed this engine to function properly with the feedback carburator. Installing an aftermarket carb negates the entire emision control system and will not allow the engine to "Breathe" properly.

I have a Weber carb on a Suzuki samurai. Runs ok but continues to try to run after turning off


this is caused by mixture getting past the idle and being sucked into the combustion chambers and being ignited by the hot spots and combustion pressures
Very common on early english cars and some american cars
The japanese carbies had a solenoid valve that fitted into the idle circuit so that when the ignition was turned off , the solenoid closed off that idle circuit and prevented the problem
you may have to "play " with the idle mixture screws to get a better mix so that the mixture is too rich to run on or change the weber to a model that has the solenoid shut off

How to fix a Weber DGV 2 Barrel Carb. I have a Weber Carb on my Model A Ford. It stalls out when accelerating up a hill. Can you help with where to start adjustments?


Sounds like restricted fuel flow...new correct fuel filter? Air/Fuel mixture...while idling...turn each screw clockwise until slight stall...then back out (counter clockwise) one and a half turns to smooth idle...Hope this helps.

I need a diagram of fast idle link assembly on weber 34DGEC carb


Tammy , weber has the pages to fix webers, why not read there.
its all there. for custom carbs,
fixing cars is a labor of love, if not, dont buy custom cars.
and for sure webers.
TAKE Photos of your work, its free now , no Kodachrome.
the car came with Autolite/motorcraft, carter or Rodcheter carb.
not webers.

idle, all carbs you can set the idle to zero. with the fly plate closed
and the engine stalls.
so does your butterfly plate close.

IDLE DOWN, HOT or cold engine,? is the choke OFF?
if the choke is off you can starve it of all air. at the stop screw.
if not, then the throttle cable is tight,
or you have air leaks in the plenum somewhere.
but air leaks cause lean, but with a bad tuned rich weber, it will race with air leaks, bingo???? im a carb o holic. retire.

1: is fuel pressure.
2: is float level checks.
3: is jetting,
4: is no intake leaks, or it will never idle right or stalls. or races.
if its rich (wrong jets) it will race with air leaks
if it lean (wrong jets) it will stall with air leaks.

5: the choke is off for all above. tuning the silly chock is last.
on my cars, i run a manual choke, so ends that.

Stock carb or weber 2 barrel whats going to best for mpg this is a daily driver 258 6cyl would like to get close to 17mpg


i would go with the weber.this is why.

Weber - This is probably the most common carb conversion for the 6 cyl Jeeps. The Weber is a very reliable, all mechanical carb that improves performance and drivability. The Weber is designed to supply the proper amount of fuel determined by the demand put on the engine. When demands are small, only the primary barrel is used, and when demands increase, the second barrel is used in to deliver the performance needed. Use of thie carb allows removal of all the electronics associated with the BBD. The 32/36 DGEV model claims 18% hp increase over the stock factory carb as well as 10-20% fuel economy increase. The 38 DGEV model is designed for higher power applications where headers, cam, and aftermarket intake manifold are used. $$

I cannot regulate the idle with my Trooper. The vacuum hoses have been replaced, carb re-built and I still can't get it to idle properly. Help! KWW


I played with mine for about 2 months trying to dial in a low smooth idle with all of the California smog stuff but it just has too many things that are hard to get that are probably just worn out. I finally opted to install a weber 32/36 and just plug all the smog ports on the manifold. Runs much smoother and has a bit more pick up

Rough idle warm up or cold


The carb may be able to be rebuilt but those old *** carbs where not very good to start with. The Weber application is a great one and will last a very long time you can also get a kit for a holley if you want to get more performance. The engine in your truck will last forever as you already know but it will start leaking oil on the front side of the engine. When this happens the tech will try to replace the pan gasket but the problem will be the front main seal. When this happens have the tech change the timing chain at same time and you will save a fortune.
