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.

    Hi,thanks for you solution...this helped me with the butterfly,it works correctly now,but I am still having the problem with the spluttering which sometimes causes the engine to cut out.This only happens when I accelerate from a stop position or almost stop and then accelerate...can you please help as my wife uses this car for work...thanking you in advance....Byron

    Glad I got something right. Next problem I suggest that the accelerator pump circuit of the carby is faulty. Check this by taking of the air cleaner and with the motor off push down on the pedal and watch for a squirt of fuel into the carby. This pump gives extra fuel into the manifold when accelerating to compensate for the fact that when the throttle butterfly is opened the vacuum drops and the fuel is not drawn into the manifold until sufficient revs is obtained to make the main jet work It may mean the carby off and a clean and new kitk

    Hello again..lol....i got a carb cleaner from Autozone and added it to my fuel....what I noteced when checking the air hoses is that two hoses were broken off from that small plastic fitting that looks like a filter,one was broken off from a fitting that is on the manifold(it has a pipe comming out and the other is blocked)now the car idils and revs like a harley motorbike and I have no power at all.I managed the glue both pipes back on,but it still has no power and revs like a bike...

  • Bill Boyd Feb 05, 2013

    REplace the fitting that is broken and the hoses also..Carby clean is not the way to go as there is a daaphram in the pump and 2 check ball valves . You have to pull the carby down to fix it.

Take a look at the fuel system. That is the fuel pump, filters and spark plugs.

Also go for a scan.

Cold start cranking problems 1987 toyota truck wont hardley crank when cold then fires fine after gets crunk till next morning


My 1987 truck I use to have had a choke and it would stick open some times. When you get in the vehicle, you have to press the gas pedal to the floor once to set the choke and add enough fuel to start the vehicle. I assume your vehicle has a carburetor and would suggest the following:

When your engine is cold, take off the air cleaner cover and base and look the butterfly valves. They are fist valve on the top of the carb air inlet. Go and step on the gas pedal once. Observe if the valves move to the almost closed position or not. If they don

1984 toyota corolla 1.6 engine. How do i adjust


Carbureted models have a fast idle cam on the throttle,It is a screw that sets against a movable part,called the cam,when the engine heats up,the cam will drop upon tapping the gas pedal.Set the carb,while the engine is cold,by tapping the gas pedal,then adjust the fast idle cam screw by turning it in,with the engine running.Start out by turning the screw in a full turn before starting engine so it will run,then adjust the screw as the engine runs.

Your automatic choke is probably sticking. Spray it out with 2+2 Carb and Choke Cleaner. Do this when the car is cold so you don't start a fire. While the car is running see what position the choke butterfly is in when the engine is hot. If it is partially closed you may have a bad spring in the choke mechanism or it may need an adjustment.

Choke won't close all the way down


I'm not exactly sure about the 1987 toyota choke, but the basic concept of a choke is that the butterfly(flap in top of the carburetor) needs to close to allow less air and more fuel to enter the intake when the engine is cold. This is acomplished on most carburetors with an electric choke thermostat. The thermostat has a bimetallic spring that is would up and connected to the butterfly through a rod. The bimetallic spring is made of a special allow that expands and contracts as the temperature changes. Usually through a relay of some sort 12v or less is applied to the choke thermostat with the engine running and used to heat the spring therefor releasing tension on the closed butterfly. It sounds like your butterfly is never opening as the engine is warming up, and staying on fast idle. See if there is a wire on the thermostat and remove it and check it with a voltmeter with the car running, there should be >8vDc. If there's voltage then the thermostat is probably faulty(as long as the linkage is ok) If there is no voltage, check the fuses and fuse links and then consult a schematic to see where the voltage is suppiled from/to, could be a faulty relay as well.

well you could try to get a vacuum gauge and see if your car reads what it supposed to and if you buy one it could tell you what it could be.
