Too much fuel when cranking engine

It seems like there is too much fuel compared to the air coming into the throttle body. Did you fit the TBI kit correctly? or is the flap in the throttle body always closed, stopping air getting in.

Son has a 1992 GMC Sierra 2500 2 wheel drive with a 454 engine. Has been using an excessive amount of fuel. Stalls at stop lights and then has to feather the gas pedal or will die. Replaced the Dis

If it has a caby then check why the float is not controlling the needle and seat that controls the amount of fuel into the carby. Check the needle and seat for something like a hair or the rubber on the needle is cracked or the seat is loose in the carby body. Concentrate on the carby as the over fuelling problem is in that area. Check that the choke is not coming on

Kf laser 5spd manual 1.6 carb

The idle circuit on the KE and KF Laser carby engines is controlled by the ignition module inside the distributor. The symptoms are intermittent stalling. There are also windings inside the distibutor that should be replaced at the same time as the module because these can short out the module.

Stalls press throttle

1st question, is that both hot and cold engine.?
2nd/ does the engine get hot? reach 180F temps. and hold.?

i feel your pain, carbs are fussy things..
for sure if the engine is health and the distributor is timed
right and advances by the book , does it?
then its a bum carb.

the problem with is fixing a 27 year old car is probematic.
back when, we can just buy a rebuilt.
or buy a kit.
we'd clean the carb , then kit it and then retune it.
now the symptoms of a bad carb,
1: it's lean.
2: what causes. lean
a: float level too low. RTM read the manual look up level spec.
b: air leaks. any where in the intake tract.
c: clogged gummed up jets, for sure in any 27 yo carb.
d: clogged nozzels
e: air jet fell out and not is tool lean, (emulsion jets)

above is for a hot motor.
if motor actually gets hot.
if the car stalls cold.?
then the choke is bad.
how do you like my carb in a nutshell post.

My 1992 Subaru Brumby Ute stalls each time I pull up or stop.

expose the carburetor throat and start the engine keeping it running with your hand on the throttle. try and control the idle at its lowest possible rpm and look inside the throat. if it is showing ANY dripping fuel or even wet flaps then it is stalling because of too much fuel and the carb. will have to be cleaned or serviced.

My toyota corolla 1986(wet look) 1.6gl automatic splutters on take off,and butterfly on carb does not close when engine is cold.

adjust the auto choke setting. there is a black plastic looking cap on the side of the carby in line with the choke butterfly. It should have a metal ring around a step held by 3 screws. loose these screws and turn the cap until the butterfly closes. You will find directional arrows on the cap which are richer or leaner. You will have to turn it in the richer direction. Ther will be a stepped cam that interacts with the throttle butterfly and you will have to ensure that when the pedal is pressed the choke butterfly closes . This sets the throttle open setting so that you dont stall the engine from 2 much choke.. Inside the cap is a bi metal spring that loosens off as the engine warms up so it is not necessary to put to much tension on the spring (what you are doing by turning the cap) as the choke will stay on longer than necessary and that chews fuel.

My car is cut off complete when i drive, but in "P"parking is no problem, what can be?

To answer your question I must put this in two parts , Firstly if the idle is low and you shift from park to drive and the engine stalls this is due to the idle being too low. When you shift from park to drive the transmission puts extra load on the engine causing it to idle lower and thus can stall. Remedy to fix is to either screw up idle adjuster but most times it's because of built up carbon in the intake throttle body causing the accelerator flap inside to not fully close . This causes the throttle positioning switch mounted on the side of the throttle body to send the wrong signal back to the computer saying that the car is not at idling position when it is. Remedy to fix this is to spray in some Carby Clean into the throttle body and then some more while the car is running, all while holding revs up on motor so it will not stall ( use the whole can ).
Now the second part is that you can have a bad wiring problem with either a broken wire or bad connector . When you put the car into Drive from the park position the engine will rock ( this is on all front wheel drive vehicles ) If you have a broken wire or bad connector some where between the motor and cars wiring loom by the engine moving it can open circuit any connection that controls engine running . Remedy to fix is to put the car into park and physically move and jiggle wiring in engine bay until symptoms occurs , then it's up to you to repair the fault

No air comes out of the defroster

The little vents (or flaps) inside the heater system are stuck, broken, lost power (they're vacuum motors).Have them check or replace.Issue can be with either a stuck or broken door, a bad solenoid or vacuum line. You'd have to take apart the Unit to gain access to these parts.

1990 suzuki sierra - stalling,

Yes your snorkel should have the right size for air to come-in, hope you have the right diameter, but snorkels will not seriously affect your vehicle substantially.
It could be that your fuel system is dirty. I would go for having those carbs cleaned but before you do this, I would advise you to clean your gasoline tank of rusts, water then blow those fuel lines with air to declog, change your fuel filters, if you do a lot of offroading, put two(2) fuel filters, first filter goes just above the gas tank, beside the chassis, the second will be place before your fuel pump, inside your engine compartment. have those fuel pumps cleaned too, check for leaks and moistures on your fuel hose and lines. if you have done all these, and nothing happened, check for strong sparks on your plugs, it could be that they ready fouled up.and check on your igniton coil,
