The first thing i would look at here is the choke pull. Make sure that after the car starts, the choke props open. Also, as the engine warms, make sure the electric choke is opening up. If not, make sure you have 12V to the choke. If so, replace it. This should solve the problem.

But let me know if you need any further assistance, ok? We'll get it working! :)

Sounds like it is time for a rebuild. Make sure the shop you take it to can tighten up the rods for the lower butterflies if they have play, because if they are loose, the carb sucks extra air that makes it hard to properly adjust idle and mixture. Hope this helps.

My toyota hiace with 2kd engine is producing a cloudy black smoke and hard stating what could be the problem


Black smoke means too much fuel .
Have you changed your air filter or is it clean. A dirty air filter will flood your engine.
Is your choke working properly?
Could be your carburetor float is sticking.
Not sure but there are computer sensors in some makes that could cause flooding if they are not working properly.
I am sure there are other things that could be the cause but you can start here.

I have a Brute Force 750, starts OK but runs rough after a few minutes, will start smoking a smelly black/gray smoke, and most recently some blue smoke.


When the head gasket fails on a liquid (water) cooled engine the typical smoke colour is white (steam) and that becomes rather underlined by the steady drop of the coolant level and often clear evidence combustion gas is leaking into the cooling system.

Smelly black/grey smoke tends to be produced by an over-fuelling condition such as a stuck choke or strangler or other cold starting aid or perhaps carburettor flooding.

Blue or blue/grey smoke is invariably engine oil burning but I suggest you ignore that until the black smoke problem is rectified and after a short time the blue smoke might also disappear. If it doesn't it could be related to the overheating but the black smoke probably wasn't caused by that...

4g15 engine carburetor smoking only when engine is cold


smoking from where?, front of car, middle or tail pipe.


is this your first car, or first car and first winter (white steam?)
there are 3 kinds of smoke
black , carb flooding (ask why)
white, oil, burning, take for ever to go away
white steam, goes away fast and smells like Antifreeze, sweet and nasty.

and all carbs smoke black in the tail pipe end, when cold, unless
you very carefully tune the choke plate.
so do tell? what?

1989 silverado 2500 wont start after it has been run a distance on the highway it just acts choked up and smokes black as it is trying to clear out


If this is a gas operated vehicle with injectors it would be strange. But if it has a TBI system then something is causing a fault so it dumps fuel and floods the engine. If this has a Rochester 4 barrel your float is faulty or the needle and seat is sticking open and dumping fuel and causing this. There is also 1 other thing that can do this and if it has a carb, it could also be the butterfly or thottle plate at the top of the carb closing from vacuum. make sure the hoses if any are connected to the choke system, and or any wire that feeds electrical current to the choke. Unless someone rebuilt it and did not correctly reassemble it. or put the choke spring on the wrong side of the notch for the upper butterfly. Then this would close the butterfly as it warms up and then choke the engine..never know..could have been a monday or friday....good luck

I have an old slant 6 carburetta engine and when i rev the motor it blows alot of grey smoke out the tail pipe


Sounds like the valve guides are worn. They will wear excessively due to the fact that
the gas currently sold has less lead content than what was sold when these motors
were manufactured. This also affects the rings as well. You could have the heads
rebuilt with new valve guides that are designed for the new fuel. The lead acted as a
lubricant. Also given the age of that engine, I would rebuild the carbeurator as well
if it exhibits black smoke, and replace the choke during rebuild. A sticking choke
will make it hard to start and plenty of black smoke. Hope this helps.

No power some times black smoke comeing out


That sounds like engine flooding, getting too much gas. Have electric choke checked for one but black smoke with drop in power must be too much gas at times.

Truck is blowing out black smoke. and if i give it gas it will run but if i let it ideal it cuts off?


Black smoke usually means the fuel mixture is too rich. Sounds like a choke/flooding problem.
